The Rolling Stones, "Stray Cat Blues"
Because they hung around so long and turned into basically Rolling Stones Inc., a licensing corporation with a neglected music production arm that would occasionally squeeze out a desultory album, it's easy for folks of my generation (old, but not super old) to lose track of the fact that for for a while there in the late 60s and early 70s, the Rolling Stones were pretty amazing. The run from Beggars Banquet through Exile on Main Street is one of the foundations of modern rock, and still sounds pretty great today.
OutKast, "Take Off Your Cool"
While I miss OutKast as a going concern, it was pretty clear with The Love Below that Andre 3000 wasn't really interesting in making hip-hop records any more. It's a big, messy record that doesn't really go anywhere. While it had some undeniable hits, it's not really something I listen to much either. Like, this song doesn't really do anything for me.
Big Drill Car, "Reform Before"
Labelmates of All, Big Drill Car played a similar brand of tuneful punk music. They didn't last long and never really picked up much of a fan base outside of southern California, but they really knew what they were doing and probably don't deserve to be totally forgotten. Had they come along another five years later with the same sound, they would absolutely have been swept up in the grunge and/or pop-punk feeding frenzies.
Coheed & Cambria, "The Hollow"
The opener of The Afterman: Ascension, which, yeah, is as pretentious as it sounds like it would be.
Swingin' Utters, "Good People"
OK, OK, check it out: if you drew a line between the Rolling Stones and Big Drill Car, you'd totally intersect...well, I was going to say the Swingin' Utters, but that's probably a lie, and I can't bring myself to finish the thought. Honestly, this particular song just sounds like a mid-period NoFX song.
