WinterWonderGrass’ Colorado version took place in Steamboat Springs this weekend, and Saturday’s festivities featured a couple of guest spots from Yonder Mountain String Band’s Allie Kral, who sat in with both Greensky Bluegrass and Fruition.

Fruition welcomed Kral and her fiddle for two tunes, “The Meaning,” off Fruition’s 2016 album Labor of Love, and “Let’s Take It Too Far,” from their new record Watching It All Fall Apart.

For the Greensky set, Kral guested on the band’s original “Worried About the Weather.” Watch a fan-shot video from that collaboration below. Greensky also welcomed a couple dobro players—Love Canon’s Jay Starling and Lil’ Smokies’ Andy Dunnigan—earlier in their set for the standard “I’m Working on a Building.”
