Shout!

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.

"Shout" is like a tent revival gone haywire, with the merest scraps of a song -- a groove and a few phrases -- igniting a soul explosion the likes of which had never been heard on record.
