They Might Be Giants, "Critic Intro"
This is the intro to Giants Jubilee, which is a comp album containing b-sides, EP tracks, and demos from the early years of the band. While there are some fun things on here, it's really only for completists.
SPK, "Retard"
Uh, sorry about the song title here. I don't really know what to do about this kind of thing, so I just leave it as is and trust my audience. Anyway, SPK were an industrial noise act led by Graeme Revell, who would go on to a long and successful career scoring films. Like a lot of early industrial acts, the ugliness was the point. There was little attempt to make this stuff appealing, it was all created as a way to get emotional reactions from people.
Black Sabbath, "Children of the Grave"
Master of Reality really cemented Sabbath's place as metal innovators, more or less launching stoner metal with this record (after having previously kicked off doom), among launching various other tricks that are still being copied by metal bands to this day.
Atmosphere, "Reflections"
After getting Felt yesterday, I actually listened to a couple Atmosphere records today, so I'm delighted to catch my favorite song from Seven's Travels here. Shit's good! Oh, also I listened to Eyedea and Slug freestyling.
The Decemberists, "Make You Better"
Folks, am I still mad at how much worse I'll Be Your Girl is than this album? I think you all know the answer to that.
