Formerly rooted in ’90s alternative grunge-pop realms, Seattle quintet Great Grandpa (guitarist Patrick Goodwin trading off on lead vocals with vocalist Alex Menne, with backup from bassist Carrie Miller, guitarist Dylan Hanwright, and drummer Cam LaFlam) have shifted gears for their sophomore LP, Four of Arrows. It’s a luxurious yet understated outing that is melodically rich, emotive, and well-orchestrated, with more pianos, more folk tendencies (picked acoustic guitars, pitch-perfect vocal harmonies), more twinkling beauty, more introspection (the songs “weave through the pains of familial divisions, partnership, internal and external forgiveness, and the struggles of mental illness”). There’s still some dissonance and guitar grit, too. This party is the official release celebration for Four of Arrows. by Leilani Polk
