Bach's Concertos for keyboard and chamber orchestra are rightly acknowledged as masterpieces of the genre, and among the first truly great concertos of the Baroque/Early Classical period. They are performed with a wide variety of instrumentation, and here Peter Seivewright plays a modern Steinway Model D grand piano, accompanied by a baroque size ensemble, also using modern instruments, but in the authentic one-to-a-part style. The continuo here is provided, again authentically, by the Spanish guitar, which gives a warmer sound than the more common harpsichord.
