Impressions of a Patch of Blue is a 1966 album by vibraphonist Walt Dickerson with keyboardist Sun Ra in a rare appearance as a sideman. It is the last album Dickerson recorded before his decade long sabbatical from jazz before his comeback in the mid-1970s. The album is relatively mainstream considering the work of the contributing musicians. An interesting detail though, is that Sun Ra plays the harpsichord, an instrument rarely used in a jazz setting.
