Solid State Survivor was the second album by Japaneseelectronic 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.
"Technopolis" is considered an "interesting contribution" to the development of techno, specifically Detroit techno, as it used the term "techno" in its title, was a tribute to Tokyo as an electronic mecca, and foreshadowed concepts that Juan Atkins and Rick Davis would later have with Cybotron. "Technopolis" was later sampled in Robert Hood's "Rhythm" from his debut minimal techno album Minimal Nation (1994), and in Electric Youth's "Replay" (2008). Techno-pop artist Aira Mitsuki pays homage to this track with her single Sayonara Technopolis, and her music video for "GALAXY BOY" is heavily inspired by that of Technopolis.
This was YMO's most successful album in Japan. It was the best selling album in the Oricon LP Chart for 1980, beating Chiharu Matsuyama's Kishōtenketsu (起承転結?) - Godiego's Magic Monkey(西遊記,Saiyūki?) was best seller for 1979. In 1980 the album won a Best Album Award (ベスト・アルバム賞,Besuto Arubamu Shō?) in the 22nd Japan Record Awards. The album went on to sell two million records worldwide.
