Minor Threat, "Filler"
The first Minor Threat song ever released, and the birth of harDCore. From the very beginning, Minor Threat was absolutely killing it. And, as a bonus, this is still one of the very best rock band names ever.
Skinnerbox, "Help Me"
This song comes from Special Wild 1989-1994, a compilation pulling together non-album tracks from the band. There are really a couple different ways comps can go. Some bands just put out their best material all over the place, and the comps become essential for pulling all that stuff together instead of trying to piece things together from the singles and EPs (the Belle & Sebastian/Superchunk route). Others clearly save their best material for the albums, and the comps then are something of an afterthought and spotty. Skinnerbox, alas, falls in this second comp. This is a record only for the serious fan.
Caspar Brötzmann Massaker, "Kerkersong"
Caspar Brötzmann is an experimental guitarist using rock as just a starting point for exploring what he can do with the instrument. His father, Peter Brötzmann, is a free-jazz saxophonist, so he clearly was raised with a philosophy of really going out there with music. I only have this one album, Koksofen, and when I got it back when it came out, I don't think I was ready for it. But I'm quite enjoying this track, so maybe I'll explore his other stuff.
Slant 6, "Eight Swimming Pools"
Back to Discord with the second Slant 6 record, Inzombia. It's another slab of the same kind of frantic garage rock/punk that was on their first record, and it's pretty delightful stuff.
TonyAll, "Telltale Signs"
Tony Lombardo was the first bassist for the Descendents, leaving the band pretty early on. In 1991, he got the guys in ALL to record an album of his songs with him, which meant he was playing with one of the other original members of the Descendents. It's not a great ALL record, but it's OK. Probably wildly unnecessary for anybody to pick up, though.
