A 12-inch of five cool covers by an unknown band on an indie label would normally rate little notice, but Georgia’s Vibrating Egg has more than just the good sense to dedicate its record to Leonard Cohen and Viv Stanshall. Raoul Duplott, the unsteady vocalist on these amiable renditions of Procol Harum’s “Whiter Shade of Pale,” Roky Erickson’s “Bermuda,” an old spiritual and two of Alice Cooper’s finest, is none other than Jefferson Holt, then-manager of R.E.M. and founder of the Dog Gone label, surrounded by a host of pseudonymous players. (Hmm…) Good fun, but Holt had best keep his day job.
