by Scott Yanow Throughout his career, mandolinist David Grisman has performed music that crosses between many boundaries, from "new acoustic" folk to bluegrass and swing-oriented jazz. This set features Grisman's string group (which also includes violinist Darol Anger , Mike Marshall on mandolin, guitar and violin, Mark O'Connor on violin and guitar, and bassist Rob Wasserman ) playing six of Grisman's diverse originals, an obscure tune, and a brief rendition of John Coltrane's "Naima." The music is excellent, but Grisman's more jazz-oriented projects would be in the future.
