Since the late '90s, boyfriend and girlfriend (and eventually husband and wife) Jason Hammel and Kori Gardner have been making hyper-joyful indie-pop music, often about how in love they are, as Mates of State. A few things have changed over the last decade. The couple now tours with their young daughters in tow, and on their 2008 album Re-Arrange Us, Gardner swapped out her signature, off-kilter organ tones for a move conventional piano, but the duo's latest record, Mountaintops, is Mates of State as fans remember them: chirpy, euphoric and incessantly catchy.
Mates of State w/ The Generationals
