During Chick Corea's freelance period after　Return to Forever　broke up and before he formed his　Elektric Band　, the pianist collaborated with many of his favorite musicians. This two-LP set contains eight duets with vibraphonist　Gary Burton(highlighted by &Senor Mouse,& &Bud Powell& and a remake of &Crystal Silence&) along with one solo performance apiece by the two masterful musicians. The music is often introspective, but there are some exciting moments.
