Actually thinking about breaks, there is of course the magnificent 20-minute plus “Break song” by Vanilla Fudge, which I urge upon you, but which doesn’t seem to exist anywhere on the internet. Though this is pretty magnificent example of the Fudge doing there hysterical yet heavy, raucous and overwrought, Purple-soul thing, James Brown and Jimmy Hendrix in a cosmic blender. And that is of course, A Riff Of Note.
Equally, much as I love “In a Gadda…” it pales in comparison to the twenty minute “Butterfy Bleu”, surely one of the weirdest splices of hard rock, prog, ambient, Clangers-style slide guitar and musique concrete robo scat funk known to man (though I’ll be overjoyed if you can introduce me to some other contenders*) and which surely must have finished off their career. Insanely it's all
And still re surprising breaks, this, while it’s quite consciously the antithesis of the other two bands mentioned above (though there is certainly a shared love of Motown going on) has some wicked and unexpected drum work in the closing minutes.
*Cue list of forty three superior examples of exactly that from the compendious Unkle Woebot.
