Two of vibraphonist Gary Burton's albums from 1969-1970 are reissued in full on this single CD. 
Burton teams up with pianist 
Keith Jarrett for five numbers (including four of Jarrett's originals) in 1970, using a quintet that also features guitarist Sam Brown, bassist 
Steve Swallow, and drummer 
Bill Goodwin. The other session has more of an avant-country flavor, with 
Burton, 
Swallow, and 
Goodwin joined by guitarist 
Jerry Hahn and violinist 
Richard Greene; Michael Gibbs and 
Swallow contributed most of the obscurities. 
Burton was at his most explorative during this period, which is why he can be considered one of the pioneers of fusion (although his music never really fit into a tight category). This is excellent music that mostly still sounds fresh. ~ Scott Yanow
