Greensky Bluegrass continued their winter tour at Nashville’s Marathon Music Works last night, and the band welcomed a couple of special guests throughout their two sets, including local bluegrass icon Sam Bush.

As Live For Live Music reports, Bush’s sit in came in the first set, when the mandolin virtuoso came on at the tail end of a “Fo Sho, Uh Huh” segment to help Greensky close the frame with their own “Demons” and “Train Junkie,” with a cover of “Sneakin’ Sally Through the Alley” sandwiched in between.

Set number two featured returning guest Billy Strings, who has been opening for and collaborating with Greensky on this tour. The guitarist came out for “Who is Frederico?” and “Burn Them” near the middle of the set. The band would later close the night with an encore rendition of the soul classic “Gimme Some Lovin’.”
