Astronauts & Heretics

Astronauts & Heretics is the fourth studio album by English new wave/synth-pop musician Thomas Dolby, released in 1992. It was Dolby's last studio album until 2011's A Map of the Floating City and his last album to be released on vinyl.

The album was met with some success in the UK. However, according to Dolby, the album went largely unnoticed in the US due to poor distribution by Giant Records and the popularity of grunge at the time.

After asking Dolby for help with his studio equipment, Eddie Van Halen agreed to play guitar on two songs on the album: "Eastern Bloc" and "Close But No Cigar", including a Van Halen-style solo on the former.

The music video for "Silk Pyjamas" was filmed on location in Cuba.
