Azazel
There are/have been over ten bands and artists called "Azazel"
1) Finnish black metal band, Azazel was never called Behemoth, that was an entirely different band (death metal) which featured Satanachia and Samiaza as members, whom eventually left to form Azazel.
Recorded a demo (purported to be a mix of death metal and industrial metal) with the lineup Lord Satanachia, Kalle Sipola, and Rotting Jesus. It was never released.
Azazel have released one demo "Crucify The Jesus Christ Again" (1993)
