Read an interview with Alex from around the time of "Grace Under Pressure," where he said he was kind of tired of guitar heroics and instead was more interested in atmospherics a la Andy Summers and the Edge. I think specifically he said he was more interested in exploring the whammy bar than offering flurries of notes, which sounds about right. It's maybe no wonder one of his most beloved solos is "Limelight," which is about as far from fast fret stuff as possible. The solo on "Chain Lightning" on "Presto" is sort of the extreme of this, for at least part of its duration; iirc the whole thing may be backwards.

What's wild about Grace Under Pressure is that prior to this, producer Peter Henderson was Supertramp's main producer.
