if you want some really trippy ambience stuff that'll freak you out pretty hard, try sigur ros. theyre definitely one of the best bands in the world if you ask me, they do a lot of work with full orchestras.
the album "takk" is their newest offering, it'll probably get you most pumped while youre riding. it's got a lot of heavy, building rhythm that really gets you jacked up. if you doubt me, just download a couple songs off of that album. glosoli and saegolopur are sooooo nasty.
