In 2003 he moved to Portland, Oregon, leading his own groups and collaborating with such bands as The String Cheese Incident, an established jam band from Colorado. The album On the Road: 06-19-04 North Plains, OR by The String Cheese Incident, released in September 2004 on Sci Fidelity, includes Law on guitar. Law then played mandolin on the January 2005 album Melting Pot by Melvin Seals, who is best known as the longtime keyboardist from the Jerry Garcia Band. By the end of 2005 Law had also shared stages with various jam acts such as the Tony Furtado Band, Phil Lesh and Friends, the Everyone Orchestra, playing guitar and mandolin and at times sharing vocals and songwriting duties. Also in 2005, during a benefit concert at Red Rocks Amphitheatre he was invited onstage by Phil Lesh, bassist of the Grateful Dead, to perform on Jerry Garcia's guitar, named "wolf." Stated Law, "To hear the tones emanate from my own fingers just as I had heard them on my first Grateful Dead albums and multitudes of bootlegs was a thrill and taught me some things. Holding that iconic guitar alone was also a mix of emotions. On one level, it's just oh well, lets see what's up with this cool guitar... while on another, it's holy shit, this is Jerry's guitar!"
