Columbia is now a subsidiary of Sony BMG, since 1988. The good part is that Sony has done some tremendous re-mastering of their Columbia catalogue... Of Dylan's early recordings, one of my favorites is... Bring It All Back Home. It has that Mercury/metalic sound Dylan said he loved when he was at his best... yeah, "Subterranean Homesick Blues"... "Maggie's Farm".... The album is like an infusion of adrenaline, with some great acoustic performances. It lifts you up.
