The String Cheese Incident (SCI) is an American jam band from Crested Butte and Telluride, Colorado, formed in 1993. The band is composed of Michael Kang, Michael Travis, Bill Nershi, Kyle Hollingsworth, and Keith Moseley, and, since 2004, Jason Hann.

A jam band is a musical group whose concerts and live albums substantially feature improvisational "jamming." Typically, jam bands will play variations of pre-existing songs, extending them to improvise over chord patterns or rhythmic grooves. Jam bands are known for having a very fluid structure, playing long sets of music which often cross genre boundaries, varying their nightly setlists, and segueing from one song into another without a break.
