Mark O'Connor was all of 17 years of age when he made On the Rampage in 1979 for Rounder, yet he was already a seasoned player attracting a lot of attention in the world of bluegrass. Overdubbing himself on violins and guitars, O'Connor shares no fewer that ten originals, which not only show a surprising maturity but demonstrate that he's a major player in stretching the supposed boundaries of bluegrass. Mark is unaccompanied for the haunting "Midnight Interlude," which consists solely of his multiply overdubbed instruments. It doesn't hurt to have veterans like mandolinist Sam Bush on hand, while both David Grisman and Tony Rice are added for the mellow "Ease With the Breeze."
