The logo could be a customized Braggadocio (http://new.myfonts.com/fonts/itfmecanorma/braggadocio/) or Futura Black (http://new.myfonts.com/search/futura+black/).

The other one seems a super-thin version of Futura.

I've investigated this one along with a few other Doors sleuths over the years. I think it's most likely that the logo was designed for a poster and then later used on the album cover. If anyone knows better, please let me know. I think it was drawn with rules/compass and not from an actual typeface with obvious influence from Braggadocio/Futura Black. I extrapolated the logo into a font called Densmore.

thanks guys..

The psychedelic typeface in the logo is Psychedelic Smoke.

»Other voices« could be L&C Hairline.
