Prepare Thyself to Deal With a Miracle is an album by jazz multi-instrumentalist Rahsaan Roland Kirk, released in 1973. Featuring performances by sixteen musicians, this is perhaps Kirk's most experimental album, with improvisational lines which are not just a series of out arpeggios playing legato and running through and over the changes, but intricately nuanced, gentle, and architecturally sophisticated wanderings. Despite the beauty of the album's first three tracks, it is on the closer, the 21-and-a-half-minute "Saxophone Concerto," where Kirk most leaves his mark as a composer and innovator on the jazz world.
