** 1/2 “Debbie Gibson Live in Concert: The ‘Out of the Blue’ Tour.”
Atlantic Video. $19.98.
Gibson, the teen-age pop star, is a more convincing artist on stage than on album. Though the best of her songs (including “Staying Together” and “Only in My Dreams”) have a catchy, nicely crafted undercoat on record, others (such as the anonymous “Shake Your Love” and the mushy “Fallen Angel”) are woefully nondescript. On stage, however, Gibson, a perky New Yorker, brings even the weakest material to life with a vitality and charm reminiscent of Olivia Newton-John’s inviting “Physical” tour in 1982. Gibson’s enthusiasm transfers well to video, though the 60-minute package is limited by rather conventional camera work and editing.
