I was thinking on my way home last night whilst listening to DFA1979, how the hell did they make such an almighty racket with just two of them?

Any other favourites?

I was arguing about this with a mate, and I'm saying:

Arab Strap

are the best. Partly due to only being 2 of them (most of the time), partly due to them being my favourite act ever regardless. These are worth a mention too:

The Kills
Underworld (in the latter years)
White Stripes
Orbital
Chemical Brothers
Fiery Furnaces

Any others I'm missing?
