John Kramer is a full time chiropractor and part time musician/composer living in the Philadelphia area with his wife, Sylvia, daughter Cori, and Yorkie, Bizbee. He also has three other grown children, Sarah, David and Aaron. Evolution was compiled in order for John to have most of his compositions in one place, mostly as a legacy for his children. Many of the pieces were inspired by and written for his wife. Although the CD has never been sold prior to this, nor has it been formally reviewed, the feedback received by those who have heard it has been glowing, citing how relaxing the music is, as well as being richly melodic. It is hoped that Evolution will be greatly enjoyed by many.
