Rising U.K. outfit the 1975 treads lightly on “Chocolate,” the lead single off its “IV” EP and upcoming self-titled album. A cocktail of bubblegum alt-rock that was recently spotlighted as an iTunes Single of the Week, “Chocolate” aims to become a top 40-friendly vehicle for the four boys from Cheshire, England. Of course, it will have to do so with lyrics that find frontman Matt Healy escaping from the police with a lover and a stash of marijuana. (“Chocolate,” after all, is British slang for weed.) “Now we run away from the boys in the blue/And my car smells like chocolate,” Healy laments as the stringy guitar line bounces back into the forefront. Drug references aside, “Chocolate” lets its sugary sweetness steer the listener toward the rest of the 1975’s strong “IV” EP.
