Isley Brothers - That Lady, Pts. 1 & 2 (1973)

"That Lady, Pt. 1 & 2" is a 1973 R&B and soul hit song for The Isley Brothers, released on their T-Neck imprint. The song, one of the group's most well known, was originally performed by the group nearly a decade before in 1964 (released as "Who's That Lady?") 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 aptly-titled album that came out that year.
