Query: Excellent technique

Ana is going to be someone to watch out for for years to come. Seeing her live is simply a rare treat in life. A true master, at least in my eyes. The only reason I rated this a 4/5 is because of her incredible speed. It's absolutely mind bogling how fast and accurate she can play, yet is speed the right thing in all situations? Example. The first track. Ana stuns you with 'how fast she can move through the piece.' I sat and listened to this track, comparing it to another master, Julian Bream. Ana moves through the piece with computer percission. Julian flows through the piece at over a minute slower. He seems to be in complete control of speed, accuracy, and emotion. Ana was quite young when this was recorded, and I have been impressed with her later work. I enjoy this recording for what it is. A young master that has perfected the technical aspect to her playing. I'm not going to say slow down, or copy Bream. Continue to grow, and develope. I'll keep listening.
