Signals was pretty good but GUP was better. Better mix, more energy and emotion, better use of synths relative to guitars, far better vocals (among Geddy's best IMO).
I think I agree with this. Two excellent albums, but some really stellar work on GUP. With Afterimage and Red Sector A, you've got some pretty emotional and personal songs, something Rush doesn't do much (until Vapor Trails, which was thick with that). Then you've got Kid Gloves, DEW, The Enemy Within, and Between the Wheels, which is more typical of Neil's lyrical style as a societal or historical observer. Only Body Electric and Red Lenses fell flat for me.
