Music documentaries are great, aren’t they? They’re a chance to really see how your favorite bands do their thing. When done right, they offer a candid look at people we all admire.

However, some docs either don’t even see the light of day or actually make their way out into the world, but fall out of the consciousness of the music community. Here we’ve collected a bunch of those that were never to be seen and those that deserve an audience.

1. Blinkumentary

This ill-fated documentary regarding blink-182’s reunion back in late 2009 never saw the light of day. While no official reasoning has been given for it not being released, many fans have speculated a number of reasons, from not enough actual band-in-the-studio footage to too much footage. Whatever the reason, maybe someday it’ll see the light of day so we can see what those sacred days were like.

2. Cocksucker Blues

A somewhat fabled documentary from the Rolling Stones, it was never officially released; but if you try hard enough, you can find bootleg copies online. In it, you’ll find footage of the Stones back in 1972 on tour supporting their classic album Exile On Main Street in full hedonistic nature. The Stones argued against its release after deciding that it may not show them in the best light, what with all the drug use, nudity and debauchery.

3. MC5: A True Testimonial

An example of when band members collide with filmmakers, this documentary on MC5—highlighting the power of their protests and kinetic live shows—took about seven years to make, yet only saw a handful of screenings. In 2004, MC5 frontman Wayne Kramer sued filmmakers as he believed he was originally promised a production credit. Eventually, a court ruled in the filmmaker's favor, but the film was never released when the filmmakers failed to secure rights to the legendary proto-punks music.

4. Kevin Smith’s Prince documentary

Back in 2002, Kevin Smith found himself voluntarily making a documentary about Prince after a failed phone call trying to secure the rights to a Prince jam for Jay And Silent Bob Strike Back, shown in a segment of his live concert film, An Evening With Kevin Smith. After spending a week with the iconoclast, the footage ended up in those mysterious Prince vaults, never to be seen again.

5. M.I.A.

One of the music industry's most vocal protestors, M.I.A., has had a documentary in the works for a fair few years now. Unfortunately, there's no word as to when it’ll see the light of day, if ever, but charting the success of such a major character who fights for the rights of those with no platform is certainly going to be an important piece of work. There's even a trailer which was released back in 2013 that you can check out.
