Batteries are not included in the Acoustic Brew Coffeehouse, a non-profit, volunteer-run concert series based in Lemont, Pa.

In fact, acts scheduled for the fall season will not use microphones, speakers, electric instruments, or sound systems of any kind. Acoustic Brew doesn't have a smoking section and doesn't serve alcohol either. In fact, one can't even order a cup of coffee. Instead, the menu prides itself on organic musical entertainment.

This season's diverse lineup of artists will perform at Lemont's Center for Well Being, 123 Mt. Nittany Rd. Now a massage and yoga facility rented by Acoustic Brew, the Center's structure was formerly a church. Therefore, its superb acoustics render sound systems unnecessary, leaving behind only the artist, the audience and the music.

For $10 per ticket, concertgoers can sample a musical hybrid of artists. Bluegrass, folk, country and gospel -- most acts embody several genres.

The concert season opens tomorrow with bluesman Guy Davis. Davis is a cultural paradox. The self-taught guitarist is an acute historian with a cutting-edge agenda. On screen, he acted in the television series, One Life to Live. On Broadway, he performed in Mulebone, a musical collaboration by Zora Neale Hurston and Langston Hughes. Davis also wrote a one-man show and other theater pieces.

Dave Carter, another jack-of-all-trades, will perform with Tracy Grammer on Sept. 29. Carter was a hitchhiker, a computer programmer and a mathematician. He spent a year meditating and analyzing dreams at the Institute of Transpersonal Psychology, and played in both a psychedelic rock band and a piano bar. At the moment, he's a country singer, citing everyone from Jack Kerouac to Joni Mitchell as inspirations. In fact, he took up the cowboy gig when he dreamed his deceased grandmother told him to move to Nashville.

Mike Seeger, a traditional music devotee, visits on Nov. 17. Using nearly one dozen different instruments, Seeger resurrects the spirit of the rural south. In fact, he's been preserving musical history on the road for more than 40 years.

Other acts include The Chenille Sisters on Oct. 13, Michael Smith on Nov. 3 and Northwest Territory on Dec. 1.

All shows start at 7:30 p.m. Tickets can be purchased from Webster's Bookstore, 128 S. Allen St. and the University Book Centre, 206 E. College Ave. Season tickets are $54.

The Center for Well Being is located about 10 minutes from University Park. For directions and additional information, visit the concert series' Web site at www.acousticbrew.org.
