Wired recommends The best SF concept albums;

• The Man-Machine, Kraftwerk (1977): It’s a six-song techno-fueled meditation on the fusion of flesh and bot. Übergroovy.
• Deltron 3030 (2000): Dan the Automator, Kid Koala, and Del tha Funkee Homosapien kick it in a 31st-century world rife with computer viruses and rap battles.
• The Heliocentric Worlds of Sun Ra, Vol. 1, Sun Ra (1965): Sun Ra claimed to be born on Saturn. Free-jazz tracks like “Nebulae” prove it.
• The Rise and Fall of Ziggy Stardust and the Spiders From Mars, David Bowie (1973): A freaky extraterrestrial becomes a drugged-out bisexual rock god (quite a stretch for Bowie). Glamalicious.
• The Clones of Dr. Funkenstein, Parliament (1976): Disco fiend Dr. F cranks out a clone army of “specially designed Afronauts capable of funkatizing galaxies.”
• Replicas, Tubeway Army (1979): Gary Numan makes one giant leap for electro with tracks like “I Nearly Married a Human.”

There definitely are a few more, esp. in Free Jazz. Ornette Coleman’s Science Fiction Sessions, for one.
