The String Cheese Incident played a secret show on Thursday night in Colorado at the Caribou Room in Nederland, CO for SCI fan’s Chris Gewald’s 40th birthday.

As Jambase reports, the band hit the stage under the name “Whibble” and performed a two-set show that saw them lean on some of their older tunes throughout.

The band is currently off the road but will return on June 24 at Electric Forest.

Here’s a look at the setlist:

Set I: Shine > Best Feeling, Walls Of Time, How Mountain Girls Can Love, Close Your Eyes, Tinder Box, Miss Brown’s Teahouse
