“Spontaneous Innovations.” Bobby McFerrin. HBO/Cannon. $29.95. McFerrin was in fine form at the Aquarius in Hollywood in February, 1986. Using his voice variously as a scat vehicle, a bass line, and on a hilarious operatic duet in which he sings the baritone and soprano parts, he runs the vocal gamut almost unaided; however, the audience joins in here and there, and Wayne Shorter adds his soprano sax for “Walkin’.” Because of the tight camera work and good sound, McFerrin comes across even better as a video attraction than in person or on records.
