James "The Manic Hispanic" Rivas has a golden voice — just a little scratchy, but warm and mellow — the kind of voice that makes you feel like you're listening to a buddy. But his pipes aren't the key to the success of his program, Cruising With the Manic Hispanic, which remains our favorite oldies show in Phoenix. It's his song selections, from Latin rockers like Santana, smooth soulsters Earth, Wind, and Fire, and lowrider oldies from the likes of Brenton Wood. Rivas' stated goal is creating a relaxing set of tunes each time he goes on the air, and when he plays songs like Switch's "I Call Your Name," with its smooth glide and easygoing vibe, it's clear he knows exactly what he's doing. But like all good oldies DJs, Rivas' line is always open for requests and, more importantly, dedications from his listeners.
