We're back by the bayou again this month, with a third helping of the ''Boppin''' variety. Ian Saddler's popular series brings more rarities and unreleased gems from the vaults of J.D. Miller, Eddie Shuler's Goldband Records and Carol Rachou's La Louisianne label. 17 of the 28 tracks are previously unreleased, so if your ears need another fix of fresh rockin' sounds from the Pelican State, then this is the place to stop.
