The bands that branched out from blink-182 take the boys' punk-infused rock in numerous—and surprising—directions. Transplants serve up frenetic, piano-driven rap-rock on “Diamonds and Guns”; Box Car Racer sparkle with a poignant acoustic shuffle on “There Is”; Angels & Airwaves bring anthemic heaviness to “The War”; and +44 rage to skittering drums and six-string overdrive on “Cliff Diving”.
