I don't think a rock band ever existed that had such consistently high caliber guitarists over multiple lineup changes. Gorham, Bell, Moore, Robertson, Sykes, White, etc etc. I'm still amazed by the quality of Robertson's blues solo on "Night Life". Guy was on point.
Love them! Huge influence, way beyond the guitarists.
As said above, fantastic different eras, each with their own gems.
One of those great classic bands that also took another dimension live.
I really enjoy TL - they've had so many fantastic guitar players over the years. My cover band started playing The Boys are Back in Town and the crowd loves it, especially the harmonized outro.
I discovered UFO fairly young and always consider Schenker to be one of my biggest influences. However for some reason, Thin Lizzy slipped past me and I've never really checked them out. I should go do that.
