One of my many theories about Sandinista! is that the reason it was initially so confusing was that it was the first Clash album where the default musical style wasn’t rock, but rather reggae. Not only are there reggae songs on every single side of the record, the last disc amps up the dub in the same way that All Things Must Pass amped up the jams.
So its not surprising that Sandinista! produced what I think is their single greatest reggae song: the monumental “One More Time.”
