Not only is Saint Arnold perhaps Houston’s most delicious brand, founder Brock Wagner (also a partner in Cactus Music) and his staff’s musical tastes are as keen as their nose for hops and extracts. As much will be on display across two stages Saturday, as Saint Arnold celebrates its 23rd anniversary with nearly a dozen homegrown acts as flavorful and unique as any of the brewery’s sudsy concoctions. Headlining are hip-hop mayor Bun B, nocturnally oriented indie-rockers the Tontons and, in the wake of guitarist Chris LaForge’s sudden passing on May 29, H-Town punk-rock royalty 30footFALL; a portion of Saturday’s proceeds will be set aside for LaForge’s young daughter. The rest of the lineup doesn’t let up, either: John Evans Band’s laconic roots-rock; both the returning Buxton and folkier offshoot Ancient Cat Society; adorably acoustic oddballs Say Girl Say; fierce femcee Genesis Blu; whip-smart songsmith Arthur Yoria; red-meat blues-rocker The Mighty Orq; and tooth-and-nail rockers We Were Wolves. For economizers, the $35 “Saint Package” covers admission, two beers and a commemorative pint glass; otherwise a $10 general-admission ticket still buys a spot at easily one of the biggest blowouts you’ll see all year.
