'''Man or Astro-man?''' are a mostly instrumental band from Auburn Alabama, they are known for combining the surf rock style of the early sixties with various samples of old, kitsch sci-fi movies, with a decided punk edge that has become more prominent over time. They're also known for covering MysteryScienceTheater3000's "love theme". Their connection to the show runs fairly deep, as many of the aformentioned samples of kitsch sci-fi come from movies that were riffed on MST3K, and Joel Hodgson has done pyrotechnics for the band's stage shows. The main members of the band go by Star Crunch (guitar, and vocals when those come up), Birdstuff (drums), and Coco the Electronic Monkey Wizard (bass & electronics). Other members have joined and left the band over the years.

!Tropes that apply to ManOrAstroMan

* EducationalSong: They've covered "Interplanet Janet" from "Schoolhouse Rock"
* GenreThrowback: After a series of increasingly experimental and abstract albums, their latest one is a return to their ''Made From Technetium'' style.
* HiddenTrack: Several, most of which are several minutes of silence followed by a brief joke.
* LongRunners: They've been touring and putting out albums since the early '90s.
* MachineMonotone: When they have vocals, they often try to evoke this or CreepyMonotone.
* MohsScaleofRockandMetalHardness: Around 6 or 7.
* NewSoundAlbum: "Made from Technetium" was a darker and grittier album compared to their previous works, and their last three albums have each been more abstract than the last.
* {{Sampling}} - of old sci-fi
* SelfTitledAlbum - ''Is it....Man, or Astro-man?''
* TheBandMinusTheFace: Averted; the members stay fairly deliberately anonymous, so if one needs to leave, the band doesn't fall apart.
