Career of Evil was a very standout track for me.
Both Queen albums released this year are excellent. Sheer Heart Attack is my favorite of the two, but they're both quality.
Queen II is an interesting one because it's one of the very few albums that seems to get respect in both the progressive rock and metal communities, yet it isn't really either. It's one of those albums where I can't really pick out specific songs as favorites, everything blends together so smoothly that I just listen to it and enjoy it as a single piece. It really does feel like two side long suites at times.
Sheer Heart Attack is one of my all time favorites. The second half has some weaker moments, but at its best it is among the greatest work Queen ever did. Brighton Rock is a really unique rocker, although I could do without the guitar noises in the middle, everything else is awesome. The real highlight of the album for me is the sort of mini suite that is Tenement Funster/Flick Of the Wrist/Lily of the Valley. I've also come to really appreciate In the Lap of the Gods after revisiting it for this thread.
Here's a pretty small detail but totally relevant to this thread. Brian May does some pretty heavy pinch harmonics in Flick Of the Wrist. This is a technique that I mostly associate with the 80s shredders such as Randy Rhodes. Later on, Zakk Wylde would go on to abuse this. It's a signature Metal thing though and as far as I've heard, no other guitarists covered in this thread have used it. I think it was one of those things that became hip once Eddie Van Halen started doing it. Later on, he would implement tapping as well in News of the World, a year before the first Van Halen.
Fly To the Rainbow continues with the more psychedelic qualities of early Scorpions, but there's some heavy material here too. The very first track wouldn't be that far out of place on Blackout, for example. But there are also extended jams such as Drifting Sun, which is obviously a vehicle for Uli Jon Roth to show off. Overall though, I think I prefer the debut. This sounds like they're caught between two sounds and are still figuring it out. There are some enjoyable tunes though, for sure.
