By now, you've probably heard of Say Anything.

The band has been featured on The Late Late Show with Craig Ferguson and Last Call with Carson Daly, and will perform on Late Night with Conan O'Brien on Friday. Its newest album -- In Defense of the Genre, a double-album released in October of last year -- reached 27 on the Billboard Hot 100 and sold 25,000 copies in its first week.

After a delayed breakout, the band is finally hitting its stride. In Defense of the Genre featured 27 tracks over its two discs, spanning screamo to showtunes and touching on everything in between. To further showcase its musical flexibility, Say Anything contributed a cover of former Wu-Tang member Ol' Dirty Bastard's "Got Your Money" for the Punk Goes Crunk compilation, which was released earlier this month.

Riding this wave of newfound success, the versatile Los Angeles pop-punkers will be headlining this year's Movin' On, capping off a 12-hour festival featuring a diverse group of acts.

We talked with guitarist Jake Turner about what it's like to play outside, why the band loves to pass the mic around and what to expect Saturday.

Q: As you may or may not already know, Movin' On is an outdoor event. What's your experience playing outdoor venues?
A: We played some amphitheaters opening for Dashboard Confessional a few years ago, and festivals and stuff are always outdoors. We'll be playing Warped Tour this summer, too, which is all outdoors. It's a totally different kind of vibe.

Q: What are the main differences? How do you approach that type of performance?
A: You have to approach it differently. Most venues have walls to cut off the capacity and to keep people in. So outdoors, the capacity is usually much higher and people just sort of wander around. It can be difficult to get an outdoor crowd as involved.

Q: So what do you do differently to make sure they're engaged?
A: When we did the Dashboard tour, it was one of the best tours we've ever done to get a crowd involved, because we were playing for a different crowd. Most of the tours we've done have been about us, headlining or co-headlining or whatever, so that tour kind of helped us to gain confidence in trying to get someone else's fans to stand up for us, to have a good time with us, even though they didn't know any of our songs. You have to be open, and a little more pushy than you'd normally be. Sometimes people are turned off by it and don't really like it, but sometimes people really like it. It depends on the crowd and the condition of wherever you're playing.

Q: Why do you think, then, that you guys are qualified to headline such a big event here?
A: I don't know. That's kind of scary. We've headlined random stuff here and there before. It's exciting. It's something that's more of an honor than an ability. You just have to take that for what it is and put on the best show you can.

Q: Your last album, In Defense of the Genre, had guest vocals on nearly every song. How do you adapt those songs to a live setting, when you don't have any of those guests on stage with you?
A: We adjust by having five other dudes that sing. We have to spread the vocals out between each other. Figure out who can sing each part, who's not playing something crazy right then and there in the song. For instance, my brother [Jeff Turner, guitarist] does a lot of the higher stuff. I do a lot more of just harmonies, and him and Coby [Linder, drummer] and Parker [Case, keyboardist] do a lot of the other actual parts. And Max [Bemis, lead singer] will sing some of them sometimes, because he actually wrote the part for him to sing originally. Whoever sang on the record just kind of replicated what he was singing.

Q: How do you follow-up a 90-minute double album? How do you top that?
A: Pretty much, Max already has the next album written. He's written a lot of it on prior tours and whatnot. He's going toward the way of having more radio-friendly song. It's not necessarily more of a poppy record or anything of that sort. It's just like a record that's very catchy, as opposed to writing a more complex, "out there" record. I wouldn't say In Defense... is necessarily an "out there" record, but there are a lot of songs on there that never would get played on the radio. This next record is definitely going to be more friendly toward people in the media, normal people. That's the way we've never really gone before. Even ...Is a Real Boy kind of throws off people, with all the different times here and there, very dramatic vocals, and stuff like that. In Defense, people were like "27 songs - that's a lot of songs to listen to. What do I do?" I think this next record is a total of 13 songs, and one of them is an intro song. It's definitely hard to follow-up, but from what I've listened to Max write, it sounds amazing.

Q: You guys are slated to play on Conan O'Brien on Friday night. Do you have any big plans for that?
A: We don't really have any big plans or anything like that. Of course we're all nervous, because we've always wanted to play Conan. That's something we've always told our label and our manager and whatnot. That's one of our favorite late night shows to watch. We're going to play our new single "Shiksa (Girlfriend)" and hopefully it'll go well. It's always a scary thing to do stuff like that.

Q: In the years that you guys have been together, what do you think has been your biggest accomplishment so far?
A: I definitely think this last tour of our we just did was a big accomplishment, taking out bands that we just loved as musicians out on tour with us and seeing how our fans would react. Kind of doing our tour where it's our tour, but we brought these bands with us, and every show sold out. I think when people left those shows, they loved all three of those other bands [Manchester Orchestra, Biffy Clyro, and Weatherbox]. Me personally, a big accomplishment was when we played Radio City Music Hall. I grew up wanting to play there for the longest time, and when we finally played there I was so scared and so nervous.

Q: So what's left? What do you guys want to accomplish in the future? What are your aspirations and ambitions?
A: I definitely think that we want to have a steady growth. We don't want to be one of those bands that gets huge for five minutes and then disappears. We want to always be around. I think we're already starting for what we wanted to accomplish. Of course, we just released a 27-song record, but I thought that was something we could do. I don't think there's any other band in our genre that could do that. I know it sounds crazy to say that, but I definitely don't think that any other band would be able to. And our first record is such an intense record to start off with. Most bands start off with a record, and you're like, "Cool. It's a good first record and they have a couple good singles." Our record was a record that, before I was even in the band, everyone I knew was talking about it, in its entirety. They wouldn't just talk about one song. They would talk about how every song, front to back, was great. I think we all just really want a steady growth into something bigger, something that's going to be around for a long time. For instance, Death Cab for Cutie, I think they've slowly built their fan base up, slowly built what they are nowadays.

Q: A lot of the people at the show on Saturday will probably be seeing Say Anything for the first time. What can they expect from a Say Anything live performance?
A: Lots of energy. A lot of crowd participation. Not necessarily like moshing or anything like that, but just having a good time, singing along, dancing around. We're all just normal dudes, but we're very awkward people at the same time, which I think makes us, as a band with a crowd, very one-on-one. We're not one of those bands that's going to say the same banter every night, like "We're Say Anything, blah blah blah." Of course we might have a set set list, but that's just being professional. We want to have fun, and we want to crowd to have fun with us.
