You know, just because Kindergarten is named Kindergarten doesn’t mean they’re like, a bunch of weenies or something. They’re serious artists, okay? Reasons to take Kindergarten seriously: Despite their upbeat funkiness, their lyrics are “dark”; one of their musicians was a Chopin scholar; and also, one of their musicians wears one of those ska hats. Reasons to go to their upcoming show: It’s free. Kindergarten plays songs from their upcoming sophomore release, Small, at Arlene’s Grocery, Feb. 8, 8 p.m., 21-plus. myspace.com/kindergartennyc.
