Only in Denver did Chris Bowers Castillo decide to recast himself into his current moniker. Tribute to Valparaiso, Indiana, where the Chilean American used to give walking tours among the street dogs and day drink, Kiltro translates as “strays” or “mutts.” His current trio’s 2019 debut, Creatures of Habit, strummed and hummed South America-leaning pop, but June follow-up-cum-lockdown-product Underbelly clicks and skips a delicate coupling of psych ambience and shoegaze, tempered by folk neorealism and Latin percussion. “[When] we added the rhythmic component,” he said, “I realized that having a bit of noise and chaos can add emotional depth.” Los Angeles folk singer Jamie Drake opens.
