FREDONIA – The 1891 Fredonia Opera House will present a special concert featuring two veteran folk music artists on Friday at 8 p.m. Singer/songwriter Garnet Rogers and folk duo Mustard’s Retreat will share the bill, each performing a set of original and beloved folk songs.Born in Hamilton, Ontario, to parents of Nova Scotian descent, Garnet Rogers spent many hours in front of the old floor model radio listening to Grand Ole Opry broadcasts and harmonizing with his brother, the late folk legend Stan Rogers. Soon, Rogers found himself playing the definitive 8-year-old’s version of ”Desolation Row” on his ukulele. He quickly abandoned that instrument to teach himself flute, fiddle and guitar.By 18, Garnet was on the road as a full-time working musician with brother Stan. Together they formed what has come to be accepted as one of the most influential duos in the history of North American folk music. Garnet acted as producer and arranger for older brother Stan from 1973 to 1983, when Stan tragically died in a plane crash.Since then, Rogers has established himself as a formidable solo artist, hailed by the Boston Globe as a ”charismatic performer and singer – one of the major talents of our time.” With his smooth, dark baritone, his incredible range and thoughtful, dramatic phrasing, Rogers is widely considered by fans and critics alike to be one of the finest singers anywhere.Kicking off the evening will be the folk music duo Mustard’s Retreat, comprised of musicians David Tamulevich and Michael Hough. Celebrating 35 years performing as Mustard’s Retreat, Tamulevich and Hough pride themselves on a long career, a feat they credit to being focused on their audiences. Everything they do on stage is aimed at pleasing, moving and engaging the audience. Whether simply singing their own gentle love songs and vivid ballads, telling tall tales or offering treasures from America’s vast traditional song bag, David and Michael always make a Mustard’s Retreat performance feel like it’s specifically designed for the people who have come to see them that day. Audiences sense this from the moment the duo takes the stage.Spike Barkin, who produces the prestigious Roots of American Music Festival at NYC’s Lincoln Center, wrote to thank the guys for their ”folk from the heart,” telling them it seemed like ”you take your living room on the road with you and invite people in as friends.”David Siglin, of Ann Arbor’s legendary Ark Coffeehouse, where Mustard’s Retreat played their first songs together, says ”in order to last there has to be more than just talent you have to enjoy playing, enjoy audiences and enjoy being in front of them. Audiences go to (their) shows because they know they will be entertained.”This special evening of folk music is part of the Opera House’s Folk in Fredonia Music Series, which is graciously sponsored by the Gilman Family. Tickets are $15 for the general public and $13 for Opera House members. Additional support for the event comes from the United Arts Appeal of Chautauqua County.The 1891 Fredonia Opera House is a member-supported not-for-profit organization located in the Village of Fredonia Village Hall in downtown Fredonia.
