"The Rev" Jeff Mosier is the founding member of Blueground Undergrass, the earliest music pioneer that merged bluegrass instruments and traditional tunes with the magnetic energy of rock and roll. The band he fronted for more than a decade had recorded four albums and built a sizable national following by combining bluegrass purism with a jam band sensibility. As the jamband scene became more jam-tronica and less roots-driven, the public formation of a more song-driven rock/bluegrass ensemble, The Mosier Brothers Band, made sense.
The band is fronted by three of the core players of Blueground Undergrass: Jeff Mosier on banjo and vocals, Johnny Mosier on guitar and background vocals, and the legendary Widespread Panic favorite, David Blackmon, on fiddle. Also backed by the solid bass playing of Col. Bruce Hampton alumni Kris Dale, alongside Atlanta drum legend Lorenzo "Lo" Sanford; a rhythm section that gives the MBB band the ability to travel seamlessly through many musical genres. The jamming is still there, and so is the intuitive musical interplay that was the hallmark of Blueground Undergrass. However, Jeff Mosier views The MBB, as a middle ground between the traditional bluegrass flavored sound of Good Medicine, a band that he and his brother fronted for 23 years, and the “wall of twang” jamband sound of Blueground Undergrass.
