TWICE AS NICE is Penny Critchlow and Mark Olson who live off the grid in the rural Sierra Nevada Mountains of California. Mark took up fiddling during the 1970s and soon became a mainstay of the Santa Barbara square and contra dance scene before moving to the mountains in the 1990s. Penny has a knack for unearthing gems from the country music repertoire and can be heard singing on Ray Bierl's latest CD, "Any Place I Hang My Hat". Accompanying themselves on guitar, fiddle, and mandolin, Penny and Mark harmonize on songs from the string band tradition of the 1920s and 30s, and the country duets of the Delmore Brothers and Louvin Brothers, among others.
