The 5th Dimension is an American popular music vocal group, whose repertoire also includes R&B, Soul, and Jazz, best-known during the late 1960s and 1970s for popularizing hits of songwriters like Jimmy Webb, Laura Nyro, Burt Bacharach, Ashford & Simpson, and others, and helping to popularize "flower power" music with both white and black middle-class Americans.
These are photos from concerts where the 5th dimension played, so they may be of other bands that played the concert as well.
