what always amazes me about Brian is how any one performer can be so good on the guitar and the concertina. And he is bloody good on the guitar. If he could sing, he would be totally amazing ...

the only parallel I can think of is Tomas Lynch, who is an incredible guitarist, and a virtuoso uillean piper.

obviously there are many guitar/banjo/fiddle virtuosi, but few on dissimilar instruments imo.

actually, this subject deserves a thread of its own ...
