Lost Penny originally formed as a duo with Erin Dahlby on mandolin and Nadine on guitar. They first met at a local bluegrass jam in Estes Park, Colorado.  Nadine had been performing solo as a singer-songwriter, and Erin had been performing in a 3-piece bluegrass band. When by chance of circumstances they were playing the same venue, Nadine spontaneously invited Erin to sit in with her.  They quickly discovered they had a compatible drive and passion to make music, and that the timbre of their voices blended well.

​Their original songs are clever and sometimes poignant, and their arrangements of covers are fresh. Their music is harmony-focused americana, bluegrass and country, but if you ask them what kind of music they play, there will be a long pause, because they don't like to be boxed in. They are free-range and prone to sing about dogs and Elvis.
