 inspired by The Impressions.After signing with Epic Records in 1973, the eldest members of the group (O'Kelly Isley Jr., Rudolph Isley and Ronald Isley) had included younger members, guitarist Ernie Isley, bassist Marvin Isley and keyboardist/pianist Chris Jasper, as official members.In a response to this transformation, the group gave themselves the moniker of "3 + 3", describing the three original vocalists in the group and three recruited instrumentalists, inspiring the title of the album that came out that year.
