snobb Second of two Keith Jarrett's "American quartet's" early 70s' recordings on Impulse! label. First one was live album Fort Yawuh which contained one of their best ever avant-garde jazz improvs mixed with Jarrett usual classic-influenced melodies.

One year only is gone, but quartet's second album is radically different. Musicianship is still of highest class, but musically Treasure Island is melodic post-bop based album. There are still some free-form improvs,but generally all album's music is groovy melodic compositions with quite well organized structure. It's interesting that if previous quartet's album was mostly soloing-oriented, this release contains much more interplays. Keith piano is very jazzy (for good), sax improvs are almost excellent. There are two guest percussionists collaborating on this alum and electric guitarist Sam Brown on two songs as well.As a result some compositions are more fusion than just post-bop, and album's closer Sister Fortune is almost rock-song - straight ahead heavier compositions almost without improvs at all.

Being quite eclectic the main problem of this album is its obvious turn to less-improvisational melodies-based more accessible music (which is so characteristic for Jarrett's "European quartet" with Garbarek he will start just few months later same year).Fortunately it still contains some best Jarrett's collaborators ever,so being transitional release could attract fans of earlier,more experimental Jarret's music,and later more pop-oriented as well.
