Both Kacey Musgraves and The Lone Bellow have played tremendous sets at Outside Lands in recent years, which is what drew me out to this show. Musgraves didn’t disappoint. She’s playing some of her new material now, including the title track of her upcoming record, Biscuits. She could easily go the Taylor Swift route and crossover to pop (she performed a great, yet earnest, version of TLC’s “No Scrubs”), yet Musgraves chooses not to go that way.

Instead, she has remained true to classic country. Good choice.

The Lone Bellow also impressed with a 45-minute set that got bogged down a bit in the middle but shined whenever the quintet either harmonized and displayed its alt-country side. For fans of the TV show “Nashville,” Humming House likely evoked a bit of “The Exes,” one of the fictional acts on the show.
