I have a lot of respect for the Beatles because they could have kept recording the same pop songs forever and still made a fortune. Yet they weren't satisfied with that and pushed the boundaries of what rock music could be. Look at all the great artists they inspired.

I like a few Uriah Heep songs but never really got into them. According to the expanded liner notes in the remastered Deep Purple In Rock album, when the mark II lineup first formed they rehearsed in the same building as a band called Spice. Spice later became Uriah Heep. According to Simon Robinson (he wrote the liner notes), Spice heard Purple playing and said we need to sound more like that! Ritchie Blackmore has always said Purple got their style from Vanilla Fudge. That's the beautiful thing about music, it can inspire artists to take an idea and make it their own.

Sam Dunn made an excellent Rush documentary called Beyond the Lighted Stage. If you like Rush it is worth watching.
