'Mindbender' by the Stringtronics (a collection of composers) is well known by anyone who has dipped into Production, aka Library, albums of the 60's and 70's. Many have sampled this beautiful gem of dopeness. In fact followers of Madlib (aka Quasimoto, etc, etc..) will recognize the chop from 'Safari Park'. The 1972 album is a classic from this vibrate other-worldly genre where under appreciated musicians and their strange and funky tunes went largely unnoticed until decades later. If you don't already possess it, I suggest you carpe diem.
