Though he admits a certain discomfort with the moniker 'King of Newgrass', Sam Bush has more than earned it. As cofounder and leader of the seminal progressive bluegrass band New Grass Revival through 18 years during the 1970s and 80s, Bush may not be the only person responsible for newgrass, the wild bluegrass stepchild that features rock n roll grooves and extended virtuosic jams, but since New Grass Revival's dissolution in 1989, Bush has certainly been one of the most brilliant of newgrasss many bright lights.
