He may hate the comparisons to DJ Shadow, but damn if Blockhead’s “Expiration Date,” the first tune from Science, isn’t a dead ringer for Endtroducing‘s “Building Steam with a Grain of Salt.” But if you aim high, most likely you’ll land high, so Blockhead should take the comparisons as a compliment. His beats are tight, especially the spliffed loops of “Roll Out the Red Carpet” and “Serenade,” and the space funk of “Cherry Picker” gives concept loops some much-deserved love. And it’s not like Shadow’s explorations haven’t inspired millions. Blockhead may not be the same DJ, but on Downtown Science he’s showing off his skill set just the same.
