Last Sunday, November 1st, we went to see Akiko Suwanai perform the Brahms violin concerto with the Monte-Carlo Philharmonic. I really enjoyed her interpretation of the concerto and her style of playing. She plays with a very rich, warm, controlled tone, without being overly flashy, which I felt fit the piece perfectly.
Here is a cross-section of what her sound looks like to me, synesthetically. The deeper tones in her sound were a nice, warm red - even leaning towards a brownish-red at times - but with an airy texture. When playing in a higher register, it was interesting to see that she kept that same light, airy tone. I also felt the shape of her sound was interesting, because it wasn't perfectly round.
