not sure I've heard of this, even tho he seems to have been in so many bands (Earth, High on Fire, Sunn)
'Preston typically starts shows by saying something to the effect of "Hi. We're Thrones." even though Thrones is a solo act.'

Yeah, he's an odd one. Always said he'd rather play in other people's bands than do his own. He co-founded Earth as far as I know and was also in The Melvins during their peak period.
