A couple nights ago I stayed up late listening to Sandy Denny.  Back in the seventies I was one of those struck by what Fairport Convention was doing musically, and by Sandy Denny's voice.  My roommate and I had albums by Fairport, Fotheringay, and Sandy.
 
Fairport Convention is important historically, especially for its contribution to folk rock in the UK, but also for some of the great musicians that have passed through their ranks, including Richard Thompson and Jerry Donahue.
 
So here's a little something to ease you into the weekend, Sandy Denny with Fairport Convention, .

I've been a huge fan of Fairport Convention since I was a teenager.  The combination of Sandy Denny on vocals with Richard Thompson on guitar is one of the best pairings I've ever heard.
 
From the same album as Dave's suggestion (Unhalfbricking), I'm particularly fond of The Ballad of Easy Rider.

Sandy singing Tim Hardin's last thing on my mind is where I go when everything else is going wrong. She was just fantastic.

Liege and Lief is one of my all time favorite albums. Tam Lin is like traditional British Jefferson Airplane. So much good stuff on there, but my favorite is probably Crazy Man Michael.

I've been listening to Judy Collins' version for about 40 years.  I never realized Sandy Denny wrote it.  Great song.  As an aside, my band covers Richard Thompson's Wall of Death.
