Brother, Brother, Brother is the tenth album released by The Isley Brothers on their T-Neck imprint on May 2, 1972. It was to be the Isleys' last studio record with Buddah Records moving on to Epic in the middle of 1973. This album also was the first to bring the younger half of the Isleys: guitarist Ernie Isley, bassist Marvin Isley and keyboardist Chris Jasper into the fold alongside their older brethren: lead singer Ronald Isley and background singing elder brothers O'Kelly Isley, Jr. and Rudolph Isley. Their second venture into rock music, they didn't betray their soul and funk roots. The album featured the top 40 hit, "Pop That Thang", and subsequent hits "Work to Do", "Lay-Away" and their cover of Carole King's "It's Too Late". The brothers also covered two more King songs including the title track and "Sweet Seasons".
The album was remastered and expanded for inclusion in the 2015 released CD box set The RCA Victor & T-Neck Album Masters, 1959-1983.
