It's not entirely clear why Tlaloc, a foodie favorite known for its sopes, gorditas and pupusas and tucked away on an industrial stretch of North Chase Street, has become a home base for a certain sect of grubby young musicians, who have filmed music videos inside the joint and hosted impromptu concerts on its side lawn. But the restaurant's owners are apparently jazzed enough about it all to give their blessing to an all-day Cinco de Mayo happening, featuring a host of local and touring experimental-leaning acts, including New Age outfit Wild of Night, burnout-jazz band Half Acid and Michael Collins, a former member of Brooklyn buzz-psych tribe Prince Rama. The big "get" comes in the form of Gobby, the in-demand Harlem producer and composer whose mystical, vaguely vaporwave-y productions incorporate hard-edged Detroit techno and noise-damaged acid house. Want a margarita to go with that?
