There are two bands with this name:
1. Qliphoth is an underground italian black metal band.
2. QLIPHOTH is a witch house duo from chicago featuring members of iron like nylon. their myspace is at http://www.myspace.com/vvvsatanvvv
Diamond Black Hearted Boy was absolutely nothing like my cursory Myspace investigation might have indicated. He was on some serious low-fi art-damaged retro-apocalyptic post-Nintendo glam Afro-Futurist rock star business.
