NYC’s Jazz & Colors event was marked by a notable surprise performance from Phil Lesh and some of his friends earlier today.

The unannounced performance by Lesh, Russo & Krasno saw a peak crowd of no more than 100 bystanders as they swerved through an improvisational musical journey.

Scott Bernstein from JamBase was able to snap a quick fan video and post it to YouTube faster than anyone else and we have embedded it below. Give it a listen, to me it sounds like a jam based around the styling of “She Said” by the Beatles (and a tune that all 3 have been known to play)
