I agree with Barbara. I think they got a hell of a lot of music and musical dynamics out of two voices and two instruments. Guitars capoed at the seventh fret against guitars with a wide open fret board to create fully realized chords across both instruments. A banduria played repeated melody or lead lines against a guitar. Harmonica and guitars. Or entire songs against the drones of Small Pipes. Maybe not virtuoso instrumentation skills but I think virtuoso stage performance and arranging skill.

Listen to Ye Jacobites By Name from The Lyceum LP and hear a song grow and expand based entirely on rising volume and dynamic structure, not on increased speed.

Ronnie did subtle little vocal dances In songs like Hot Ashphalt and the Jolly Begger because it was his stronger instrument.

Two voices, two instruments. Great stuff.
