In Brief

* * “Poncho Sanchez: A Night at Kimball’s East,” Concord Jazz Video ($14.99). Taped at the club in Emeryville, Calif., with Sanchez and two other percussionists as potent rhythmic centerpieces, this is a pleasant entertainment-oriented hour, almost a nostalgia trip to the Cuba of Batista’s days. Here everything is on the move--from musicians to dancers to cameras. The arrangements and the performances by the horn players compensate in enthusiasm for a general lack of originality.
