Gorillaz, the world’s first virtual band, are the alt-universe creation of Damon Albarn of UK rock outfit Blur (“Woo-hoo!”). Del was all but left for dead by American rap audiences that often discarded quality MCs with the quickness in the ‘90s. But recycled by Albarn, he sounded fresh as new on “Clint Eastwood,” the first single off the G’z debut, Celebrity Takedown. But we prefer the less-dreary follow-up, “Rock the House,” with horns, pumping bassline and hot Biz Markie vocal sample, which delivers on the title’s promise. House sufficiently rocked.
