The return of Papi Fimbres has been one of the more exciting things to happen musically in Portland all year, since it means a handful of the city's best bands are back in action. Orquestra Pacifico Tropical is one of those. The 11-piece cumbia practitioners made a triumphant return last month during the Treefort Music Festival in Boise, and they'll make an equally triumphant return to Portland with this stacked Holocene lineup. The band's percussive thrust is accented by soulful injections of keys, psych guitars, horns, and lots of yelping, making their live show an aural excavation of some of your most basic primal urges. Dancing shoes are practically required—listen to their fantastic 2014 LP, Rio Frio, for proof. RYAN J. PRADO
