Some of these solos are really sticking out to me now.
Especially since the members mentioned some of them.

Santana is full of those memorable solos now that I think of them.
But some of Slade's stuff springs to mind too.
And Blue Oyster Cult's "Don't Fear The Reaper".
The solo in the album version of that song has the effect of thunder and lightning bursting from the sky.

Also Sweet.
Not too many solos I remember (Exception being "Lost Angels". Sweet was an early glam band that thought the New York Dolls, Mott The Hoople Image was too femmy, and would'nt show themselves on front of album covers in the late seventies).
But their brand of rock(hooks a plenty) was a pre-curser to eighties metal, if there ever was one.
Also Thin Lizzy's layered guitar prototechnics.
