From childhood, Catherine played the family piano, located in a nice warm living room...an instrument choice she made after seeing her sister's violin practice banished to a dusty, dark storeroom. She took up accordion and melodeon as an adult and has lived under the threat of eviction ever since, both from home and from MicroGrass. She shared the stage with Good Company Band at the Cove, a club at which Joe Walsh frequently performed during his Kent State days. On multiple occasions, Catherine has enjoyed the stage with Harry Tuft, father of folk music in Denver and founder of the Denver Folklore Center, as well as local favorites, Rocky Mountain Jewgrass and the Penguin Rodeo Band.
Tom started playing banjo in college but switched to guitar when, like Catherine, his roommates threatened to evict him. He's been jamming with various folk, bluegrass, and Irish groups in the Denver area for a long time. Tom Currently leads weekly Denver Retrograss jam sessions at the Historic Cameron Church and Whole Foods locations around town. He also plays with and arranges music for the Celtic band, Lots O' Irish.
Paul Marino played guitar and banjo back east with Desperado and shared the stage with Country Cooking when Pete Wernick and Tony Trishka were cutting their teeth. Desperado went on to play the college circuit and performed with Commander Cody, Orleans, Aztec Two Step, the Outlaws, Livingston Taylor, and Pure Prairie League, among others. He continued to play with Lone Rangers and Blue Skies, and was a sometime studio bassist at Fingerlakes Recording before moving to Denver. Paul still dabbles in guitar, banjo, and blues harp when the mood strikes, although he is, at heart, a bassman.
Besides playing banjo & fiddle with MicroGrass, Gordon plays in a free improvised music group, Animal/object. He has recorded and played often with Grammy Award winners Lost Bayou Ramblers, as well as co-produced France's all-time biggest selling album of a French band, Louise Attaque. In January, 2018, Gordon was feature vocalist in the Tasmanian Symphony Orchestra in Australia.
Eric Peterson was raised as a trumpet and piano player. His grandfather, who was a jazz lover and great fan of Miles Davis, wanted Eric to become a great jazz trumpeter. As it turned out, all of Eric's heroes were guitarists. In 2001, Eric co-founded Bagneo and toured Denver for many years. His most recent project was the rock trio, Sierra Hotel. However, Eric has a strong love of bluegrass music, and spent recent years studying mandolin. His extraordinary talents help put the "bluegrass" in MicroGrass.
