I was asked to take part in an art series by Sam Walton: 'portraits of musicians performing, silently and internally, music of particular significance to them.' You can watch the resulting bizarreness here.
It also got me thinking about this piece Pensiero by Frank Bridge that I learnt as part of one of my viola grades aaaaaaaaaaaages ago. It was the first piece I had to learn that I didn't view as a bit of a drudge, something to get through to pass an exam, the piece was far removed from the maths-precision cardboard of Bach, I actually felt something playing it; so cheers Frank for making me not ditch the viola.
