I incorrectly attributed the strange background noises on "Astro Vision" to unspecified electronics. (In the early days of Ra-ology, Phil Schaap opined that Sunny was playing synthesizer on the piece--we've come some distance since then.)
Hartmut correctly identified what was happening in his 1994 discography. Thanks for pointing out that there is a conga hiding under all the reverb, too. I don't know, of course, who might have been playing the conga, but the reverb points straight to our friend Thomas "Bugs" Hunter. So the suspects are: Ronnie Boykins, bass: Bugs Hunter, drums; unidentified, conga.
