I can comfortably do 3-9, but 3-10 is a stretch :)
You managed Fri 17 Feb 2006 to Sat 10 Mar, 2007 without trouble...
More than anyone else, Jack white. Listen to the riff in screwdriver, two chords and some bends, but just outrageously good.
Dave Davies, just for the solo in all day and all night, I used to listen to it on repeat, and It still puts me into silly grin mode when I hear it.
The Young Brothers "Simple, Hard hitting blues riffs coupled with boogie beats and flailing solos, while the whole thing was screwed down tighter than a coffin lid" (c) Kerrang.
Jimi Hendrix. I remember hearing purple haze and listening to it on repeat for about 3 days. Just blew me away.
And when I started playing guitar, I bought led zep I-IV, physical graffiti and how the west was one. The first three tracks of how the westt was one are all masterclasses in riffage.
Nowadays
Keef, for being just so damn cool
Rory Gallagher
And Ive been getting more into punk recently, so Ron asheton (the Stooges), Johnny ramone, and Steve Jones (the pistols)
