"Stanley Jordan: Magic Touch." Sony. $16.95. This 19-minute music cassette is strictly for those interested in static close-ups of guitarist Jordan's unusual technique. Instead of strumming or picking, he plays the guitar fretboard like a keyboard. He's like trumpeter Wynton Marsalis--all dazzling technique and no charisma. Jordan's soulless classical approach to jazz is just plain boring. This lifeless production desperately needs flash. It includes three in-concert selections--"When You Wish Upon a Star," "Touch of Blue" and "Jumpin' Jack"--and one video clip, "The Lady in My Life."
