Few pickers have toured harder or traveled farther than jamgrass veteran Vince Herman, who co-founded the iconic Leftover Salmon 34 years ago in Colorado. Yet there are always new things to try, so he’s added the band The High Hawks to his list of collaborations. Our sit-down visit was sparked by that band’s album Mother Nature’s Show doing so well on the Americana chart and by his own recent move from Colorado to Nashville, where he’s become a hub of the picking scene and an avid co-writer. We cover a lot of ground from his origins in Pittsburgh and West Virginia to the everlasting desire to play the next show. Also in the hour, progressive banjo player Kyle Tuttle calls in from a fishing trip to talk about his years with Molly Tuttle and his new solo album Labor Of Lust.

John Leventhal is one of the quiet achievers of American roots music going back more than 30 years. Early on as a guitar player in his native New York City, he connected with Jim Lauderdale and Shawn Colvin, co-writing and producing their debut albums. He met his wife Rosanne Cash as they worked on the pivotal album The Wheel. He’s produced some epic albums since then for William Bell, Sarah Jarosz, and others, winning numerous Grammy and Americana awards in the process. At last, he lent his guitar and studio skills to making the solo debut album Rumble Strip. Rosanne is there for some duo vocals, but otherwise it’s warm and tuneful instrumentals that foreground some of the lovely textures and grooves that have been behind so many albums we’ve loved.

History was on Béla Fleck’s mind as he released Rhapsody In Blue on Feb. 16, the 100th anniversary of its 1924 premiere. It's a multi-faceted, album-length celebration of the great work of American music - and its adaptability. The centerpiece is a 19-minute classical version by the Virginia Symphony Orchestra with Fleck playing Gershwin’s tricky piano part on banjo. But there are blues and bluegrass versions of the piece too. Because even at age 65, when he could be coasting on all he’s done, Fleck still looks for apparently the hardest thing he could possibly try at any given time.
