This year's summer bop options were more abundant than ever, between Arts for Art's Vision Festival, 92nd Street Y's Jazz in July, and the mammoth new CareFusion spread. Still, it's the free Charlie Parker Jazz Festival that keys us in, so to speak; the annual alfresco weekend, split between Marcus Garvey Park in Central Harlem and Tompkins Square Park in the East Village, is excellently curated by the City Parks Foundation to include all genres and be as virtuosic, yet accessible, as the Bird himself. This year, Voice favorite Vijay Ayer delivered a staggering late-afternoon set; it was pure poetry that Sir Parker would have loved.
