Bach is one of my favorite composers. I just recently heard Julia Fischer perform his violin concertos and she is awesome! She's also cute, which doesn't affect the quality of her work, but I'm sure being cute is not bad for business
Her album with St. Martin in the Fields is just wonderful (and inexpensive)! She also plays a bit faster than other recordings I've heard, but it's a nice change of pace. Her technique is awesome, and she sounds great! Highly recommended.
