of course, the #1 destination of any Z-lister should be Downtown Music Gallery 342 Bowery [between E. 2nd & E. 3rd Streets] http://www.dtmgallery.com/ for new and used. also good are Other Music (4th and Broadway, around the corner from Tower records) http://www.othermusic.com/ for new noisy stuff, electronic, and indie rock. the used selection seems weak Kim's Music & Video (many locations, 6 St. Marks btw 2nd and 3rd is convenient to DMG and OM.) www.kimsvideo.com more noise, improv and indie, again with weak used. by far the best used classical is at Academy Music 18th Street btw. 5th and 6th avenues Includes a good contemporary classical section, halfway decent mainstream jazz, and even a tiny "experimental" jazz section. The whole store is devoted to used discs. For a decent selection of mainstream CDs and a few bucks discounted, go to J & R Music World at Park Row (across from City Hall). I'd love to see what anybody would add to this list - this is my whole routine.
