Although the Yonder Mountain String Band was formed in Nederland, CO, its origins go back to Urbana, IL, where college student and banjo player Dave Johnston met mandolin player Jeff Austin. Austin moved west and settled in Nederland. Johnston joined him there, and the two met bass player Ben Kaufmann and guitarist Adam Aijala at a club called the Verve. In December 1998, they formed the Yonder Mountain String Band to open for a band at the Fox Theatre in Boulder.
