The Black Apples live in a house painted a half-garish, half-charming purple, nestled beneath the high-rise trees of downtown Fort Collins. In the short five months that The Black Apples have been in town, they’ve established their house as equal parts roof-over-the-head, practice space and social enclave. During more than one Black Apples concert, the boys have offered party invitations over the mic, welcoming folks to follow them home after the show for continued boozing.
