by Scott YanowThe superb trio (pianist Phineas Newborn, bassist Ray Brown and drummer Elvin Jones) had never played together before but it didn't matter. They had little trouble finding common ground. The virtuosic pianist (still in peak form) leads the way on such pieces as his "Harlem Blues," "Ray's Idea" (composed decades earlier by Brown) and Horace Silver's "Cookin' at the Continental."
