Bass Player / Bassist looking for Doom Stoner Grunge band - London

Hi, I'm a thirtysomething American bassist looking to join or start a serious originals band with a heavy Doom / Stoner / Grunge sound.

My influences are, to name a few:

Black Sabbath, Electric Wizard, Soundgarden, Sleep, Melvins, Clutch, Stone Temple Pilots, and the blues & blues-based rock in general

Some of my demos:

I'm based in Watford, but London rehearsals are no problem. Also spend a lot of time in Croydon.

No offence, but No beginners please!
