Nowadays several bootlegs exist and there's one official single vinyl repress from 1998 that almost looks the 1st pressing.

If you want to be sure if your copy is the original 1st issue check the following characteristics:
1. 1st pressings will always have the "DMS cg ☮" signature etched in the runout grooves as well as the "HuB" etching.
2. The label of the single vinyl reprint has the same wild pitch logo on white background, but there's a slight difference: 1st pessings have the Main Source logo straight above the center hole, not sideways.
3. I have heard that '98 reissues have a different label adress. Make sure copy will have this Wild Pitch adress on label & sleeve: 231 West 29 Street, NY, NY 1001.
4. A further hint is the front sleeve. Some reprints (not all!) have a blown up photo on the same sized cover. So if the ear of Large Professor is cut off you owe a repress.

There are 1001 reasons why everyone should own at least one HipHop LP - this is one of them. Breaking Atoms remains largely undiscovered by many due to the LP being released on the now defunct Wild Pitch label resulting in it being out of print for a long time. The album was pioneering primarily for its excellent production, which made sublime use of the SP1200 - a dedicated sampling drum machines but also from the tight rap skills shown by the Large Professor. In addition, the LP also helped to establish the careers of both Akinyele and Nas. I won't offer a breakdown of the LP track-by-track suffice to say that they're all quality and contain no fillers. Do yourself a favour and check it out.
