The 40 Watt Club is a music venue in Athens, Georgia. Along with CBGB, the Whisky a Go Go, and selected others, it was instrumental in launching American punk rock and new wave music.
The 40 Watt Club had its origins as Curtis Crowe's 171 College Avenue loft back in 1978. Bill Tabor and Crowe joked that it was a 40 Watt Club due to the single 40-watt bulb which hung from the ceiling.
In May 1980, Crowe and his partner Paul Scales moved the "club" a few doors south to a space above a sandwich shop at 100 College Avenue and renamed the club the "40 Watt East".
In April 1981, with new partner Steve Allen, Scales migrated the club to a larger space at 256 West Clayton Street. Amenities such as a stage and hot water were added, as was a second bathroom.
Doug Hoechst bought the club from Allen and Scales and, in 1983, moved it to 382 East Broad Street and renamed it "40 Watt Club Uptown".
In 1987, when rents increased on the space, new owners Jared Bailey and Barrie Buck (then-wife of R.E.M. guitarist Peter Buck), moved the club back to its West Clayton Street location.
In 1991, the 40 Watt moved to its fifth and current location at 285 West Washington Street, the former Potter's House Thrift store building.
