ECM celebrates the occasion of pianist Keith Jarrett's 70th birthday with two simultaneous releases. One is a classical date for its New Series on which he performs piano concertos by Béla Bartók and Samuel Barber with two different orchestras. The other is Creation, a solo piano offering. While Jarrett has made dozens of solo records, this is unlike any in his catalog. Rather than document the unfolding of his in-the-moment ideas through a single performance, this set features nine sections compiled from half-a-dozen performances in four cities and five venues (all notated in the sleeve) during 2014.
