Ron Wall has been a strong supporter of the autoharp community for many years, as a player, a producer, and an innovator of the instrument. The development of his personal style of bare-fingered open noting has amazed listeners for decades, and together with his singing and songwriting skills, make him a delight to hear. He last performed at MLAG in 2015, and this will be his fifth appearance as a featured performer.

Ron has taken the autoharp into the world at large with his many well-known commercial recording projects featuring acoustical instruments, such as the “Old-Time Gathering” and “Smoky Mountain” recording series he produced. In 2002 his ambition, drive, and support brought into being the legendary “Autoharp Legacy” 3-CD set featuring over 50 autoharp players from around the world in solo and duet formats.

Ron’s design of his Mountain Harp in the early 2000s is one of the few modern re-workings of autoharp construction. Tailored to sound best when played bare-fingered, and using guitar string gauges, it is sought after by players who value its unique timbre.

He helped initiate the Autoharp Jamboree at the Ozark Folk Center in Mountain View, Arkansas, and the Walnut Valley Festival in Winfield, Kansas, where he became the International Autoharp Champion in 1994. He has also lent support in many ways to MLAG and other autoharp festivals past and present.

She was an early adopter of diatonic tunings, and of Ron Wall’s open chording style after seeing him demonstrate it in a workshop. She began teaching at national venues such as the Augusta Heritage Center in West Virginia and Chicago’s Old Town School of Folk Music in 1987.  Today she remains active at events and venues such as Seattle Autoharp Week, the California Autoharp Gathering, England’s Sore Fingers Week, and the Ozark Folk Center.

June Maugery

June Maugery grew up in Massachusetts, the oldest of seven children in a family that enjoyed and supported musical endeavors. After discovering the autoharp in the late 1970s, she was enchanted by its sound, terming it “harmony heaven,” and the rest is history.

June’s most influential mentor was the late Marty Schuman, who encouraged her to expand her style to what we enjoy hearing from her today – a wide range of genres, from graceful songs to driving fiddle tunes. She enjoys jamming, especially at night, usually providing a harmony line, either on autoharp or vocals. A familiar face at MLAG, the Swannanoa Gathering in North Carolina, and many other musical festivals, she enjoys getting together with other musical partners in duos or band situations.

June lives in France with her husband Bernard, but spends much time each year in the U.S. visiting relatives and playing music. She was the 1997 Mountain Laurel Autoharp Champion and has released two recordings, her own “Shining Bright Like Gold” and “Old Time Journey” in collaboration with Mike Fenton. This is June’s fourth time on the MLAG stage as a featured performer.

Cindy Harris and the GrayScale ContraBand – Cindy Harris has been making and teaching music with voice, autoharp, fiddle and a variety of other instruments for as long as she can remember. She is particularly interested in traditional music of many varieties, and her repertoire includes everything from Irish tunes and Israeli dance music to dark Appalachian fiddle tunes from the mountains of West Virginia. But her playful side can’t resist amusing modern songs about real life, which somehow co-exist with folk songs from long ago. A concert set from Cindy is always a collection of eclectic surprises bound together by a common theme that suits the occasion.

As a member of the Pittsburgh traditional music and dance community, Cindy formed the contradance band GrayScale in 2018. With a repertoire based on traditional fiddle tunes, GrayScale placed fourth in the 2018 Neo-traditional Band competition at the Appalachian String Band Festival in Clifftop, WV. GrayScale is a favorite contradance and square dance band in Western Pennsylvania, and performed at several festivals while touring Australia in 2020.

Cindy placed second in the International Autoharp Championship every year from 2013 through 2016 and won that contest in 2017, earning her a spot in the 2018 Champions Concert, where she performed in a trio with guitarist Bill Balassi and concertina player Jody Kruskal. She played in the Mountain Laurel Autoharp Championship every year between 2008 and 2019, missing the final only once, placing in the top three seven times, and claiming the championship in 2019.

Cindy has two recordings of her own, “You Can’t Get There From Here” (2006) with her daughter Rebecca Heath, and “Potluck!” (2018), a collection of autoharp duets with fifteen other fabulous autoharp friends. She was also included in the 2003 “Autoharp Legacy” project and appears on autoharp or fiddle on a number of other recordings. She has produced and also appears on three autoharp-related recording projects with members of the Cyberpluckers autoharp discussion group: a 1999 recording of the music of Stephen Foster, and two volumes of “Strike The ‘Harp” featuring a wide variety of holiday-related music (2009 and 2013). All of her recordings are available at

She has remained active behind the scenes where she can be found ensuring the annual success of the MLAG Silent Auction and currently participating as a member of the selection committee for the Cohen-Grappel Autoharp Recording Grant. She is also the long-time moderator of the Cyberpluckers.
