Not a patch on his dad [1], though

- and he cheats, too - banjo pegs with stops for retuning on-the-fly mid song

Overall he's a fine guitarist, got a good voice, but personally i find him a bit pretentious - YMMV! I guess that having a luminary of the UK folk-rock scene (and wonderful guitarist/singer/songwriter, and a bit political even at 60) as dad, and Jimmy Page as a visitor for jams with dad through his childhood, he was bound to pick up a few tricks - especially the open tunings Dave H. (The engineer formerly known as Homeless)
[1] Roy Harper - if you've not heard his music, do so! Anyone who can get Led Zep dedicating a song [Hats off to Harper] deserves a listen
