Cellist Natalie Clein has recorded the Elgar concerto, part of which you can hear on her MySpace profile. The CD is out now:
and available from amazon.co.uk, for example. I'm a great fan of her "Romantic Cello" compilation, so I'll probably complete our Clein collection at some point.
PS Here's the Indy on Sunday on Natalie's first busking experience earlier this year.
