Solid State Survivor is the second album by Japanese electronic music band Yellow Magic Orchestra, released in 1979. Solid State Survivor was never released in the United States, but many of the songs from this album were compiled for release in the States as the US pressing of ×∞Multiplies (1980), including the tracks "Behind the Mask", "Rydeen", "Day Tripper", and "Technopolis". Solid State Survivor is only one of a handful of YMO albums in which the track titles do not have a Japanese equivalent.
