Rick Henn spoke about it in the Sunrays “Vintage Rays” linter notes. The exact quote is such:

"He (being Dennis Wilson) had us record some guitars and piano rolling chords down one octave than usual with the tape machine at half speed and then when we played it back at normal speed, it shot everything back up an octave and gave it a kind of shimmering mandolin/string, bowed tremolo effect in the background.“

I’ve been meaning to ask for quite awhile, but does anyone know if Eddy Medora ever finished the autobiography he was working on in the early 2000’s? I always assumed that he didn’t prior to his passing, but sometimes I find myself re-reading his EarCandy interview (https://www.earcandymag.com/sunrays.htm) and I think about if he finished enough to ever have it put out in some form? It sounded like there would be some amazing nuggets related to Murry and Dennis, specifically, and it’s a shame that some of these stories might never be heard.

Anyone know anything more about this?
