I just discovered this band recently and really love their debut LP on Tee Pee Records Neptune With Fire.
Ancestors is a psych/progressive/doom metal band from L.A. They formed in 2006 as a three piece slowly adding 2 more members.
This release features only two tracks both of which are pretty long. The first clocks in at 16:46 and the second at 21:38. So you can imagine that with all the sub genre references given, these are pretty epic songs.
Give this a try. If you're a fan of all or any of the Doom Metal sub genres, you'll love this...I would hope.
