From their website:
"Hailing from Minneapolis, Minnesota, ZEBULON PIKE is an instrumental prog-doom metal band formed in late 2002. Inspired in equal parts by heavy sounds of the 70's (Mountain, Pentagram, Captain Beyond, early Judas Priest), progressive rock (King Crimson, Rush), and 20th century classical (Bela Bartok, Arvo Part, and many others).
ZEBULON PIKE combines the impact of metal with the considered approach of 'art' music. The result is a rather refined, muted aggression necessary for inciting the slow motion apocalypse."
