John Corzine


John Corzine has been part of the southern California acoustic music scene for more than 40 years. Festivals and contests, Disneyland and dance floors, coffee houses and concert halls — John has performed throughout the southland, having gathered a collection of some of the best bluegrass, old-time, country and folk music you’ll find.  Influenced and inspired for life by meeting Doc Watson at age of 9 years old, John spent his early years in local flatpicking and clawhammer banjo contests and began performing bluegrass and old-time music professionally shortly thereafter.  John performed and toured with Philo/Flying Fish recording artists Jim Ringer and Mary McCaslin, and was featured on Mary’s A Life and Time album.

John has played in many area bands over the years, often with his wife Peggy Corzine on bass and vocals. John and Peggy currently perform with their youngest son Cody as the Corzines, and you can hear him this summer with the Coyote Brothers at the California Bluegrass Association’s Father’s Day Festival in Grass Valley, CA.  John comes to Camp for the first time this year to share his teaching and performing experience in the use of the guitar as a lead instrument, as the rhythmic foundation in a bluegrass and old-time band setting, and as the melodic and complementary background to vocal performance.

Joe Craven


 After 40 years in the biz, Joe Craven wears a lot of hats; instrumentalist, vocalist, producer, actor, storyteller, visual artist, noisemaker, fashion insultant, former museologist and creativity educator. He enjoys ‘playing forward’ folk tradition and process by mashing ideas and sound tools from a variety of unexpected places creating new music altogether.

As a multi-instrumentalist, Joe has made music with Jerry Garcia, David Lindley, Alison Brown, Howard Levy, Vassar Clements, Rob Ickes and many other innovative artists. As an award-winning educator, Joe has taught with jazz vocalist Inga Swearengen, bassist Victor Wooten, children’s music innovator Paul Reisler and jazz percussionist Jason Marsalis and he’s been a featured artist/educator in the PBS television Music Gone Public series. Joe has also created music and sound effects for commercials, soundtracks, computer games and contributions to several Grammy-nominated projects.

He’s presented at over 500 schools, universities, music camps and the American String Teachers Association. Joe is a keynote clinician at Wintergrass in Seattle and a coast-to-coast Master of Ceremonies, having emcee-ed at a wide variety of music festivals, including DelFest, Grand Targhee and Telluride Bluegrass. A recipient of a Folk Alliance Far-West Performer of the Year Award and the Swannanoa Gathering’s Master Music Maker Award. From Carnegie Hall to street corner busking around the world and back – Joe’s at home and loving every minute. David Grisman shared the following about Joe: “Everything Joe touches turns to music.”

Dave Firestine


Dave pulls out the “take no prisoners” style of playing at every dance – bringing the tunes to their full potential and beyond. He is a tune-meister and music jams are super fun when he is in the driver’s seat.

Originally a drummer, his strong sense of rhythm and syncopation is the foundation of his playing and tune writing, and truthfully he is never happier than when he gets to pull out the laptop drum kit to back swing and honky tonk tunes. Don’t worry, he can access his sensitive side when playing waltzes and beautiful melodies.

Dave is a music vagrant retiree now, but before that, he was Senior Gyzmologist building lightning detection systems. He is currently playing with the dance bands STEAM! (www.dancetosteam.com) and The Privy Tippers.

Martin Grosswendt


Martin Grosswendt has been exploring the roots and branches of American acoustic music for more than 50 years, having cut his teeth on his older sister’s LPs of Mississippi John Hurt and the Kweskin Jug Band. A master of pre-war blues and other southern traditional music, his fingerpicking, bottleneck playing and singing move audiences, critics and musicians alike. He’s played at festivals, concerts and music camps across the U.S. and Canada. His musicianship is matched by his knowledge of the music’s sources and creators.

Sylvia Herold


Sylvia Herold covers a broad stylistic spectrum.  For 16 years she toured and recorded with the popular San Francisco Bay Area swing trio Cats and Jammers.  She was a five-year member of the Django Reinhardt-inspired Hot Club of San Francisco, and she performs with Wake the Dead, a band that melds traditional Celtic music with songs of the Grateful Dead (whodathunkit?)  Her Sylvia Herold Trio plays smoking-hot swing and standards, and she’s the lead vocalist of Euphonia, a quartet that blends traditional folk music from America, the British Isles and beyond.

She’s an impressive guitarist and vocalist, comfortable in a host of styles, and has recorded many, many works with the A-List of Bay Area musicians.  She’s taught at a variety of camps over the years, and is highly regarded as an instructor.

You can see much more at Sylvia’s website, and some fine videos.

Tim May


Tim May has taught for a bunch of years at the Colorado Roots Music Camp.  He’s also one of today’s hottest flatpickers, period.

For fifteen years, he performed with the progressive bluegrass band Crucial Smith, playing most of the high-profile festivals in the country including Telluride, Winfield and Winterhawk.  In 2002-2003 he toured with Patty Loveless in support of her bluegrass albums Mountain Soul and White Snow: A Mountain Christmas.  In 2005, he recorded on Charlie Daniels’ album Songs from the Long Leaf Pines, and was solo guitarist on the Grammy-nominated track I’ll Fly Away.

Tim has also toured with John Cowan Band, performed at the Grand Ole Opry as a member of Mike Snider’s Old Time String Band and played on the all-star Rounder recording Moody Bluegrass: a Nashville Tribute to the Moody Blues, of which Mark Hurley of Higher and Higher, the Moody Blues fan magazine, said “The jaw-dropping guitar solo on The Voice would cause Eddie Van Halen to weep from insecurity.”

Of his playing, Pat Flynn said “Tim always says that I influenced him, but the truth is that I’ve learned something every time I play with him.  I owe him a lot,” and Dan Crary said simply, “Tim May has just become one of my favorite guitar players.”

She is a veteran touring performer of the folk coffeehouses from Boston to Seattle, as well as The Cowgirl Hall of Fame, Carnegie Hall and on the Jerry Lewis Telethon. “You can’t make it into double digits, and continue touring for twenty or so years, unless you know what you’re doing, and do it well,” wrote The Chicago Examiner.
