The Heat Is On

The RCA Victor & T-Neck Album Masters, a brick of an Isley Brothers box set, contains 21 albums from the beloved vocal group, nearly all expanded with single mixes and other assorted rarities. A close listen to the collection underscores how they may have been reliable but they were never static. They were keenly aware of emerging trends, and hearing these albums back-to-back underscores that progression.

1975's The Heat Is On was the third album that the Isley Brothers recorded with their 3 + 3 lineup, and by that time, the lineup had really perfected its attractive soul/rock sound.
