Query: Stunning! The Standard to Compare Against. A Classic

Stunning! Bach's brilliant and beautiful Brandenburg Concertos still amaze me after hearing them so many times. They are, without question, masterpieces. Bach realized music that transcends our normal definition of music. Just listen to the CD.Of all the versions I have heard and/or own of the Brandenburg Concertos, this CD is the best of the first four concertos. It is the standard to compare against. That is why it has been chosen as a Penguin Classic. MUST HAVE!The crispness, mood, and overall sound are sublime. The virtuoso playing is masterful. And the pieces are legendary. Everyone should own this CD.
