If you like some songs by The Clash, listen to some today. Why not? Get reacquainted with their broken Spanish, deep lyrics, and ska-styled youth-outrage. Start with Something About England, for its horrific relevance to today.
If you like The Clash, you can’t go wrong with “one of the five weirdest albums of all time,” the original Sandinista! album. It is wacky, weird, has great cuts, and a short clip of schoolchildren singing Guns of Brixton. Warning, this album is long, and you kinda gotta like The Clash.
If you actually like The Clash a lot, do yourself a favor and check out The Sandinista Project, a collection of Clash covers. The site linked is about the creation of the album, but the album itself is pretty good (read: interesting), with a couple of standouts that I like better than the originals, notably Junco Partner by Jon Langford and Sally Timms. Of note, it does not include my very favorite Clash cover, The Guns of Brixton by Nouvelle Vague.
If you like The Clash like I do… you already have all those things. Carry on, you marvelous bastards.
