The Flaming Lips are one of those bands with mountains of music to their name. Wayne Coyne and his ever-morphing cast of collaborators are 35 years deep into a wildly prolific career in which they’ve never seemed to stop creating — albums, EPs, demos, side projects, collaborations, elaborate performance-art stunts, music packaged in candy skulls, you name it. In fact, they’ve been at it for so long and changed so much that their oldest material now feels like the work of a fresh new band to be discovered.

That’s where the Lips’ new archival project comes in. They’re releasing two remastered collections of their earliest recordings this year. First up is a single-disc compilation called Scratching The Door: The First Recordings Of The Flaming Lips, which will be out 4/20 (of course). They’ll follow that in May with a six-CD box set comprising their output for Restless Records called Seeing The Unseeable: The Complete Studio Recordings Of The Flaming Lips 1986-1990.

The surf-rocking “The Flaming Lips Theme Song 1983,” from Scratching The Door, has never been released online before and was previously only available on an extremely limited 7″ in 2013. Hear it below, where you can also check out the tracklists for the various projects.
