Symbiosis is an album by jazz pianist Bill Evans with an orchestra playing a two-movement work composed by conductor Claus Ogerman, recorded in February 1974 and originally released on the German MPS label. It was the third orchestral album by Evans and Ogerman, following Plays the Theme from The V.I.P.s and Other Great Songs and Bill Evans Trio with Symphony Orchestra, which mostly consisted of relatively brief arrangements of works by other composers, modern and classical. Ogerman said that his composition is divided into two "entirely opposed night pieces." He described them as follows: The tranquillo of the second movement releases the inner tension of the first. However, both movements share one joint foundation. The second movement is almost in its entirety a repeat of a fast 41-bar 16th-note woodwind/saxophone passage of the first movement. ... This transfiguration is preceded by two new largo themes for piano and accompanying orchestra. The piano concludes the piece by establishing once more the D-Major theme of the first largo. The work's two movements are divided into subsections.
