UBO are still sending out the stoney vibe, son. Humid grooves touched with light horns, you know? But with City Breakers, Up Bustle & Out’s stepping away from the Peruvian flutes and radio rebelde politics of past albums and heading into some rooftop reggae dub, and it’s a nice trip. “Bob Your Head” has a smartly snappy rap. “Rainbow,” a full and satisfying dub mix, has a slowly wavering horn that floats up thick and hazy like the blur of hot air rising from a summer sidewalk. And “Dance Your Troubles Away” is the mandate your citystompin’ ass won’t be able to resist.
