I was thinking how strange it is that I've not only never seen these guys mentioned here, but also that I don't remember ever having had a conversation with anyone about them (even in person). And I don't think I've ever heard them on the radio except maybe their old psych classic "Pictures of the Matchstick Men" on an oldies station long ago. The reason this is strange is that they were one of the biggest selling bands in the UK in the 70's. They had three #1 albums and one #2 from 1973-75, when they had among others Led Zeppelin and the Stones for competition. Not only that, but I doubt Hard Rock as it exists today would be the same without them. I'm sure they influenced AC/DC, Foghat, Thin Lizzy etc. They were a pioneering twin guitar boogie band, and a very popular one too.
Here are my recommendations if anyone wants to check them out.
1. Blue For You- #1 UK album, probably their heaviest, although they never were super heavy. More like an uptempo basic Wishbone Ash.
2. Quo- Similar to "Blue For You". #2 in the UK and both available on 2 on 1 CD.
3. Ma Kelley's Greasy Spoon- Really the beginning of their hard rock era. An under-rated album that was crucial to blues based boogie rock. Also heavier than it's reputation.
4. Hello- Another #1 in the UK. Very uptempo and poppy.
5. On The Level- Similar to Hello, also a #1 seller. Also available together on 2 on 1 CD. These two were their most accessible and poppy, but not very heavy really. A lot of energy though.
6. Dog of Two Head- A more diverse album, but very good. Somewhat of a regression to their Psych era after "Ma Kelly". Most of their music is very basic, but this one has some depth.
7. Piledriver- This got some promo in the USA. But it's over-rated and over-titled. I think this album ruined whatever chance they had here. People bought it expecting "piledriving" rock, and got at best a good natured buzzsaw. Not their best IMO.
It's funny that they now seem to be remembered mostly for inspiring the NWOBHM band Vardis, "Quo Vardis", etc.
