These UK cellists (articles here and here) give new meaning to "scaling the heights" of cello playing. I would definitely take the Luis and Clark carbon fiber cello were I to follow their footsteps!
And here's a nice tribute to Eugena Slezak, retiring from Concordia College. "She made us laugh, she made us cry, she made us proud to play cello. Ms. Slezak was probably the best teacher I had. She was tough and that’s part of what made her great. I learned much more than cello skills from her." What more could any teacher want to hear from her (or his) students?
