Pink Floyd, during their transition phase of 1970. I'm not sure if I ran this concert last year, but it's a good one and it features Pink Floyd during that seminal period of time when they were exploring new areas and evolving from their legendary Syd Barrett period towards what would eventually be their iconic Dark Side Of The Moon period. This is a half hour excerpt of a longer concert, with many thanks to BBC 6 Music for making these classic concerts available online. I would urge you to go over to their site and check them out - they are a treasure trove of material a lot of people on this side of the Atlantic probably haven't heard before.
But in the meantime, enjoy this one for your Saturday night.
