Query: superb performance

this is just beautiful music.perahia is a true keyboard poet and Zubin mehta is perhaps the most underrated conductor ever(i have seen his performances on the TV a couple of times with the new york philharmonic.i have not heard any other conductor shape beethoven's third piano concerto as well as this fine conductor).in these chopin piano concertos they fashion a fine blend of lyricism and athletic vigour.the slow movements can make the listener hold his/her breath ,the poignancy is gripping!watchout for the final movement of the first concerto where the piano catches up with the orchestra in an athletic dash for the finishing line!
