Rave legends push boldly into uncharted territory

Packed with cameos from Q-Tip, The Charlatans' Tim Burgess and Bloc Party's Kele Okereke, 2005's Push the Button was the Chems' most song-oriented effort to date. Exhibit A: "Galvanize", a rousing hip-house number that’s powerful enough to shout along to. Tackling winsome alt-rock, steely dance-punk and even Bollywood breaks, the duo bend all manner of styles to their will, and on cuts like the flamenco-infused funk of "Shake Break Bounce", the results are truly out of this world.
