I'll have to have a listen, Dave, and see what I think. I still scour the internet for pieces of prog rock which I never noticed back in the day, but it's slim pickings. I recently downloaded 'Ashes Are Burning' by Renaissance because it was recommended as their best album by enthusiasts, but I have found it a bit meh.
I'm going through an electric blues phase at the minute. The car sound system is reverberating to Watermelon Slim, Johnny Winter, Mike Zeto, Stevie Ray Vaughan and Johnnie Williams Blues Band. Great stuff.
