In their debut performance, dubbed "a tribute to Sun Ra," the Afro Polyphonic Space Orchestra displayed why the approach of their oddball jazz-pioneer hero still sounds not just out of time, but out of this world. Playing as part of the first annual Afro Roots World Music Festival at Tobacco Road, the A.P.S.O. filled an entire outdoor stage with members from a broad spectrum of Miami's music scene -- from straight-ahead horn players to an R&B bassist, from a rock guitarist to an electronica keyboard maven. Decked out in glittery blouses that looked as if they'd just been stolen off the back of a truck at Mardi Gras, the A.P.S.O. proceeded to jam out on a variety of Sun Ra's Arkestral standards. Hopscotching from wiggy Dixieland to mind-melting fusion, it wasn't long before the ensemble stepped off into the void, chanting "we travel the spaceways" as disembodied saxophones dueled with eerie blasts from a Moog. Theirs was a freaky musical ride like no other on Earth.
