Info from Wikipedia
The 688 Club was a popular alternative music venue in Atlanta, Georgia, located at 688 Spring Street, near the intersection of Spring and 3rd Streets. The 688 Club opened in May 1980 and closed in November 1986.
During the early 1980s, the 688 Club was the primary place for up-and-coming bands from Atlanta and Athens, Georgia, to get noticed. Among the groups that regularly played there were R.E.M. and Pylon.
The club re-opened as the "686 Club" on December 31, 1986, but was renamed "The Rollick" the next day. By 1990, the space was occupied by a club called "Weekends". The club was operated by an Atlanta attorney as an industrial/goth club known as Tyranny from 1995 - 2000. The space was later occupied by Outa Control Inc. Sometime thereafter, the original building was extensively remodeled, and as of July 2012 houses a Concentra urgent care medical facility.
