Best known for the track “Pretty Boys and Pretty Girls,” which was one of the first songs to address the AIDS epidemic of the late ‘80s and early ‘90s, Book of Love first gained exposure by opening for Depeche Mode in 1985 and 1986. The snyth-pop four-piece reunited for a one-off Houston show in April 2013, but announced the following June that they were working on new music. They’ve been touring ever since. The band hit SA for a performance at Maverick Music Festival last year, and is returning for two sold-out performances this week.
