Several references upthread to squeaking noises caused by repositioning of fingers on guitar strings. It can sound cool sometimes, but it’s the result of sloppy technique or a difficult passage and is not something that guitarists do intentionally. Although I’m sure there are skilled guitarists who consider it “not broken so doesn’t need fixing,” the truth is that it’s the kind of thing that tends to disappear from your playing once you become mindful of technique. It’s comparable to scuffing your feet or standing with poor posture. I’m only saying this because someone asked about it.
I recall hearing once on the radio an extended version of Sir Douglas Quintet’s “She’s About a Mover.” IIRC, as the music fades away, there’s some guitar work and someone responds by shouting, “Hey! Who let that freaky guitar player in here?” I’ve looked for this version unsuccessfully for so long that I’m starting to wonder if I didn’t dream it or something. Actually, I was going to post it here in an “identify this” thread, so here goes: If anyone’s heard this version, please let me know.
An old recording I’ve mentioned here before: “My Sweet” by Django Reinhardt and Stéphane Grappelli. The whole thing is bristling with optimistic energy, especially Django’s supercharged strumming, heard at several points but especially at 1:33 here.
An even older recording is Blind Blake’s “West Coast Blues.” Again, I’ve mentioned it here before and the whole thing is full of great playing (kicking every guitar player’s ass since 1926). One detail I like is how he introduces his solo with “I got something gonna make you feel good!” at 1:38 here.
The rhythm behind Muddy Waters’ version of “Still a Fool” (Two Trains Running) sounds weirdly disjointed, largely due to a trippy little repeating guitar riff but also because someone is thumping away on a bass drum (I read that it was Lester Melrose). Once every couple of years, I love to get very drunk and listen to this really loud in a dark room. I’m not going to indicate a specific part; just crank up the volume and enjoy.
Bukka (Booker) White’s “Fixin’ to Die Blues.” Mushmouthed delivery throughout, but notice how his voice changes timbre for some lines of verse (“That’s why I tried so hard and come back home to die”).
ZZ Top’s “Jesus Just Left Chicago” has some blisteringly hot moments. The music, of course, but also in the singing (“Turning muddy water into wine”).
Robin Trower’s “Too Rolling Stoned” and, in addition to the smokin’ guitar, someone in the crowd yelling “Hey, that’s alright!” at 7:02-7:03 here. Another one to crank up real loud.
