[6] Through the next several years, Clapp was involved with a number of independent music projects in Boise, and went on to collaborate again with members of Haggis - this time with inclusion of Birnbaum.

[7] The label continued working with regional bands to release their EPs and albums under the moniker STMC (Spudtown Music Collective) until Clapp relocated to the East Coast.

In early 2001, Clapp moved to New York City, and within months was hired on as drummer for a Warsaw Poland Brothers US tour, performing for the first time with the band in New Orleans with no audition or rehearsal.

"[10] Skeleton Key continued to tour the United States and Canada with Clapp in the band, and recorded songs which would eventually go on to limited release as The Lyons Quintette EP.
