A band fronted by Jared Leto that plays quite good music but has a nasty habit of making very pretentious music videos
30 Seconds to Mars' videos that are pretentious include: "The Kill", "Kings and Queens", "From Yesterday", "Closer to the Edge.

Fucking kick ass band! With an interesting stellar concept of glyphs and cyphers.
Their album will take you on a trip, kick your ass and then bring you back wanting more.
