DTC - regards the music expertise. I'm not so good I can tell just by listening, but if I knew the underlying chords on the solo I could be more sure. Using StephaneGuitars slowed down clip, I think what you mean is at 0:33 - and it sounds like a Key Change. It sounds good though doesn't it? It really lifts the solo up and moves it along.
For guitarists, think of key change as just playing the same pattern of notes (scale) a few frets further up or down the fretboard. So either a key change in the middle of the song (as per solo), or the same song played in a different key between versions (Elevation tour vs 360 for example). All a Capo is doing is changing the KEY of the Open Chords. So instead of playing everything on the next higher string (5 semi-tones higher) I would just put a Capo on the 5th fret and play it the same way I am used to but higher up the fretboard - but that's because I am lazy. It's how I did my cover of EBTTRT.
