You better have Saxophone Collosus! By far, best Sonny Rollins album. If you're into that, check out Gerry Mulligan meets Ben Webster. Also, Kind of Blue needs to be mentioned (for people reading the thread, if you like Rollins, you already have Kind of Blue). The Quintet at Massey Hall is also really good. Total all star line up - Charlie Parker, Dizzy Gillespie, Max Roach, Bud Powell, Charles Mingus. The best live lineup I've ever heard of.
