All you metal fans seriously need to check out
Zebulon Pike.
"Zebulon Pike is doom-laden instrumental stoner metal, and the soundtrack to the slow motion apocalypse. Embrace the sad wings of destiny..."
I saw them recently and they blew my fucking mind! I've seen lots of shows so that's saying alot.
A couple of their songs they played were around 30 minutes, and they rarely repeated any parts! It just a constant bombardment of heavy riffs, dual lead licks and broken music box-like quiet sections. I can't even begin to understand how they write their songs, let alone play them live.
Also, Savage Clone likes them, so they have some kind of random seal of approval for that.
