I heard about this band a while ago, Stagnant Pools, from KEXP. Thank you KEXP. Thank you. Why? Because Stagnant Pools fit a hypnotic niche in my brain. They are so amazing. They are here tonight, at the Neptune, opening for David Bazan. Don’t care about David Bazan? Still see this duo of brothers from Indiana. 9 PM/all ages/$18.
