The music you heard up until the Claptrap portion.....THAT WASN'T DUBSTEP!!!!
Completely opposite. The music before the claptrap portion is the original style dubstep. The music you hear when the claptrap dances is the more recent version that people refer to as wubstep/brostep.
gamezrochard posted... It's techno house before CT.
No. The song in the trailer is "Doomsday" by Nero, a dubstep/drumandbase group from the UK, although they're heavily influenced by Daft Punk, so there is a little bit of that French House feel to it too.
