In 1991, singer-songwriter Jim Brunberg joined the duo, forming the folk rock band, Box Set, that began performing locally, and after establishing a growing loyal fan base, regionally.

Twain, who was unable to travel due to his day job, left the band, leaving the Box Set Duo, which still continues to perform on occasion in the Bay Area and Portland.

[2][3] The increasingly popular duo, whose expressive songwriting and resonant harmonies have prompted comparisons to Simon & Garfunkel,[4] decided to broaden their sound by adding drummer Matt Abbott and bass player Chad Heise in 1993 and keyboardist/harmonicist/accordionist Sam Johnston in 1994.

In February 2009, he recruited former Box Set members Matt Twain (keyboards, vocals) and Mark Abbott (drums) as well as former college friends Eddie Berljafa (bass) and Jeff Ballard (harmonica, percussion) to form The Fall Risk, which debuted on June 20, 2009 at the San Gregorio General Store.

[16] Shortly thereafter in 2010, The Fall Risk added former Box Set member Sam Johnston (organ, accordion, pedal steel) and Rich Goldstein (rhythm/lead/slide guitar) (who performs with drummer Mark Abbott in his band Little Muddy)[17] and added "Fiddle" Dave Muhlethaler (fiddle, mandolin) and Phil Savell (lead guitar) in 2011;[18] Eddie Berljafa returned to the band, replacing Dave Moffat at that time, as well.
