Technically not a new recording, so I'm posting here...
I've happily discovered that NPR's "Pipedreams" programme has a cd available that includes the late Robert Pitman's transcription - for piano and organ - of Mendelssohn's first Piano Concerto. This was a piece that I first heard broadcast back in 1988 - and never thought I would hear again. I think the combination of piano/organ works wonderfully in this piece.

Maybe that letter-writing campaign to Michael Barone paid off (though it took 20 plus years) :D
