Yes, it's a fascinating connection. Maybe Sharrock heard the "desert blues" somewhere
My vinyl is dead quiet, not warped and of a standard weight. I don't have an original to compare to, unfortunately. The sound is good to my ears on the released version but is a bit boomy and unsubtle on the other. I'm no audiophile, as this blogger appears to be, and I'm happy to own this as Lanquidity is one of my favourite Ra's.
