Underthings are a soulful vocal trio propelled by a supple rhythm section of drums, bass and guitar. Their sound blooms from funk, rock, punk, and Motown roots and sometimes branches into Bollywood and tropicalia. Underthings' music is described as “Anthemic ceremonial satire” by Tim McKee, Managing Editor of The Sun Magazine. Listeners have been reminded of the Velvet Underground, David Bowie, the Beatles, Os Mutantes, and Hedwig and the Angry Inch.
Vocalists Brad Erickson, Courtney Arnold and Olivia Rathbone are veterans of alt-musical theater productions such as DayGlo Yodel and Apostasy of the Sea Monkeys. Drummer Jason Berkman keeps bees and also keeps beats for Baby Seal Club and Parlor Tricks. Bassist Sarah Topaz can also be heard playing the low notes for Illusive Soul.
