A few of them:
Another Brick In the Wall, Part 2, skip to 46 seconds. I’m counting about 10 [high] chords just a few beats after Roger says ‘hey, teacher, leave them kids alone’. (note, the chords start just a few seconds after :46). I melt into my chair when I hear those…from the first time I heard them. Sometimes I still rewind it that riff and listen to it 3 or 4 times.
While we’re on Pink Floyd, there’s the ‘opening’ part of something that I love…turns out it’s the entirety of In The Flesh, I suppose that doesn’t count then.
Not really a ‘short moment’, but Mamas and the Papas, California Dreamin’, as much I a sing along (when I’m alone), for some odd reason, I sing along with the back up on that song, love it. While that also goes for Come See About Me by the Supremes, I rarely sing along with Supremes songs, Diana Ross’ voice…I can’t even.
Led Zeppelin, Whole Lotta Love, after Bonzo’s solo, Jimmy does…something…to me it always sounded like a swarm of bees, it’s the part that moves from L to R if you’ve got it on Stereo instead of mono (and no, it wasn’t a bow, that was other songs). Gives me the shivers, I love it.
Led Zeppelin, the opening bass riff of Dazed and confused…you just know you’re in for a great song that you don’t hear often.
As long as I’m on opening riffs, I’ll toss two more your way, The Immigrant Song and Roadhouse Blues. Again, you just know what’s coming and especially with The Immigrant Song, it’s a great pick me up. Oh and BTW, if you like that song, I encourge you to check out the lyrics, they’re really interesting (in a lyrical sense). I love that song but really never knew them, even knowing them know they’re too tongue twisty to sing along with them. As a confession I never knew them until I saw this (warning, autoplays, and kinda loud, but if you like it, check out more stuff from rathergood).
I could go on and on.
