A friend once commented that Sextant by Herbie Hancock was a very round record. I believe he was talking in the context of synesthesia, the abstract condition where senses cross polinate and to him the electronic tribal rhythms and bleating Moogs of one of the most palatable fusion records did indeed sound round. It didn't help his argument however that this was around 6am, we were all severely medicated and stood directly over a deck, watching Sextant spin round.
There is a form of mild synesthesia working in Australian band Alpine's Gasoline. bright, orangey brightness, maybe it's those guitars but it is bright like Houses of the Holy or Len's immortal Steal My Sunshine and comes wrapped in the hyperactive child cuteness of early Sugarcubes
