Membran presents a 20 CD series of jazz productions that were originally released in "long play" format 12-inch vinyl believed to have gone missing. These classics, gems and long-lost rarities were from selected sessions from the beginning of the 1950"s, when musicians first started taking advantage of the revolutionary possibility of extended improvising on longer titles - which is why the series contains many jam sessions and superstars. Booklets contain discographical details, which were often missing from the original LP covers. Wilbur DeParis
