I've checked out some OPN, but not enough to really get into it. For ambient and drone stuff, I dig Keith Fullerton Whitman and Stars of the Lid, though I haven't been listening to that type of stuff very closely in recent years. I definitely like Bonobo, I think it actually fills a similar niche to Wagon Christ in that it's electronic music with some experimental tinges that's still accessible and could be played for a mixed crowd without a lot of people saying "uhh WTF is this?"
Music is actually my primary passion. Went to music school and got an essentially useless degree in electronic music (haha), but that's neither here nor there. Played in bands ranging from covers to indie pop to post rock. Been to lots of music festivals (Bonnaroo 03-07, Lollapalooza 05-09, several years of Pitchfork,etc.), but didn't have the time for that last summer.
Funny how vaping and good musical taste seem to go hand in hand.
