Brits in general, and hip-hop samplers in particular, think that Roy Ayers' 1970s R&B work encompasses his finest period. As usual, these people are wrong. Before Roy Ayers went soul, he was a mainstream jazz vibraphonist. This 1969 set balances string-laden ballads with intricate bossa novas. Joining Ayers are Herbie Hancock and Ron Carter on sumptuous originals and hits of the day. A beauty.
