Not criticizing anyone's taste, That would be rude, ignorant and pointless, just a bit surprised at how consistently the metal/ hard rock genre seems to be favored. I love Zep by the way, a proper, loud, blues band. Just struggle a bit when they get into Tolkein territory. Was very lucky to see them at the O2 for the Atlantic records blokes memorial reunion. Great to see the kids jaws drop when they realized how loud and messy these old geezers were. John Paul Jones also involved in a nasty little band called Them Crooked Vultures with Dave Grohl from Nirvana/ Foo Fighters. Worth a listen, my rockin friends.
I like a load of stuff, but core tastes were defined by Thames delta r'n'b - the Feelgoods - and 76-77 punk, ska and reggae. All disposable stuff, but heavy on attitude.
For the Floyd fans, check this out. It has Gilmours seal of approval
