Finally a talk show host who knows what he's talking about! Elvis Costello is certified and dignified. Wednesday marks the premiere of "Spectacle," a new music-themed talk show on Sundance Channel hosted by Costello. Basically it's a musician's version of "Inside the Actor's Studio" without James Lipton's endless list of mundane questions.

The guest line-up for the upcoming season includes Elton John, Lou Reed, Jenny Lewis (who teamed up with Costello for a track on Acid Tongue), The Police, She & Him and Rufus Wainwright. Each episode opens with Costello and his band performing a song. Following the interview, Costello and the guest come together for a duet.

While other channels focus too much on the tabloid-y side of celebrities' lives, Sundance Channel has got it right. Shows like "Iconoclasts" and "Live from Abbey Road" offer viewers an introspective glimpse at the creative process and the development of one's vision from its earliest stages. Here, seeing legends and colleagues chat for a leisurely hour is just as informative and fun.
