^ I share quite a lot of those thoughts.
First half was an enjoyable listen (your bootleg), but the second half just kind of meandered; not untypically. That was only the fourth gig in & last year Buckethead was unforgivably (if you'd been there) sloppy early on in the tour; but late bootlegs are awesome in terms of his playing last year. This year/tour is likely to be the same. On that, pretty curious to what the plan is here. Tour is still only a handful of dates then a big gap, then the Halloween date (album preview?), then the new year dates (the live album recording perhaps?) Doesn't make much sense. Primus are touring mid-October into November with no support announced (bar one date with Clutch, who they just toured with) which nicely coincides with the gap in Buckethead's schedule. I wonder...
People keep talking about jamming but it didn't really hit off, did it? Honestly, they don't sound that rehearsed; and Buckethead & Brain haven't been on stage together for easy a decade. So it's not surprising it's this rough sounding. Oddly enough, Buckethead actually "jammed" to his own backing tracks last year better than this. And, like you say, on some tracks Monti & Brain are just totally under-utilised. They're just plodding along playing backing for Buckethead e.g. Soothsayer. Which, as you say, is hardly the current set highlight. I think I'd probably have loved the show, but I can see why people who have seen him before would be disappointed. It's hard to think why a guy who seems so carefree & who-gives-a-fuck in terms of releasing music is so conservative in terms of setlist choices. There needed to be more effort & more rehearsal(s). This honestly feels like a warm-up tour. Really hoping they step up a bit.
Btw, your audio genuinely is pretty damn good. Good to hear you thought the sound quality at the gig was good too; always hard to tell from YouTube & bootlegs. And in respect to BHL3; I honestly can't imagine what would make me that excited to be truthful. A really well produced, cohesive album is... well, just going to be another album. He's done so many different styles of albums (not all particularly good) already so it's hard to see where he can go here. Altho' an album with Travis again would be fucking awesome. He's basically going to have to do all these things to keep people happy. Expectations are unrealistically high when you compared him to other artists.
