Last year, he gave a guitar clinic at the festival; this summer, Mark Lettieri puts his lessons into practice when he appears with his Mark Lettieri Group. Audiences can look forward to his humorous presentation, but especially to the seemingly careless accuracy with which his fingers glide across the strings of his baritone guitar. Lettieri smoothly alternates funky rhythms with razor-sharp solos, never losing sight of the cohesion of his compositions. On Spotify, the Grammy winner himself curates a playlist of artists with whom he has recorded. The long varied list includes Philip Lassiter, 50 Cent and David Crosby. Lettieri has toured with soul diva Erykah Badu, among others, although most fans know him best for his work with Snarky Puppy and the Fearless Flyers. He has released six albums under his own name and Deep: The Baritone Sessions Vol. 2 (2021) is the latest.
