Infrared Roses is a live compilation album by the Grateful Dead. It is a conglomeration of their famous improvisational segments "Drums" and "Space."Somewhere in the middle of the second set of a Grateful Dead concert came a period of musical improvisation. This part of the concert is commonly referred to as "Space," and came right after a drum solo or duet. Infrared Roses is a compilation of these performances. There are no recognizable songs from the band's repertoire on this release.
