The International Submarine Band (ISB) was a country-rock band formed by Gram Parsons in 1965,[1] while a theology student at Harvard University and John Nuese, a guitar player for local rock group, The Trolls. Nuese is credited with having persuaded Parsons to pursue the country-rock sound for which he would later be remembered.[2] Parsons' work with the band predates his better known ventures with The Byrds, the Flying Burrito Brothers, and the Fallen Angels with Emmylou Harris
