This should be interesting, if for no other reason than it’s a new variation in the history of local vinyl-spun lore. Arcata Soul Party is going to be a DJ-curated dance party, but not at Humbrews. Tonight’s grooves are going down at Septentrio at 9 p.m., where a $10 sliding door fee will allow you access to the dance floor. Tonight’s ambassadors of shimmy shimmy ya are King Maxwell and L-Boogie. Viva.
