Isley Brothers, The Vinyl Records
First formed in the early '50s, the Isley Brothers enjoyed one of the longest, most influential, and most diverse careers in the pantheon of popular music -- over the course of nearly a half-century of performing, the group's distinguished history spanned not only two generations of Isley siblings but also massive cultural shifts, which heralded their music's transformation from gritty R&B to Motown soul to blistering funk.
