I think that the Solo Bass Guitar CD is the only Squarepusher album that I didn't bother buying - those three words 'Solo Bass Guitar' were enough to put me off, no matter how big a fan I am.
I watched the first fifteen minutes odd of this show. Maybe it's because it was only on iPad speakers, but the whole thing seemed to be very upper-register, like guitar territory. Lots of flamenco-style chords and fingerpicking. Also not a fan of that half-fretted buzzy note thing that he seems so fond of. The more rhythmic and riff-based he became, the more I enjoyed it.
Last time I saw him play, it was an hour and a half of fit-inducing bombardment-of-the-senses electronica, with a ten minute interlude for solo electric bass. That's more my kind of show.
