Over at the Internet Cello Society Forums, there is an interesting thread asking the following:
"Turns out I have collected over a dozen CDs of the Dvorák Cello Concerto over the years (and who knows how many LPs). So I thought it would be fun to make a compilation of a number of well-known cellists playing a good portion of the exposition of the first movement.
My hope is we can make comments on the actual playing, without our judgements being filtered by our preconceptions about a particular player.
So my gentle request is that if you recognize a performance (as many will), don't post the identify the cellist--yet. After we've had a while to discuss the performances, we can play "guess the cellist" and I'll post the identifying information.
What do you like, what don't you like about each performance? (Some things we might want to focus on: tempo, rubato, phrasing, tone, use of vibrato, articulations, overall effect.) Do you like one better than the others? Why?"
I have found it helpful to do the stretching exercises my physical therapist recommends. Do some core strengthening exercises, such as the ones highlighted at The Mayo Clinic. By keeping your core strong, your back won't put itself in a position to cause that sciatica pain you are having.
