Of all the bands that shouldn’t feel compelled to reissue every album in their catalogue as if it were one seamless canon, Pink Floyd shines on the craziest.

The band’s eras couldn’t get Amy more distinct: the period when Syd Barrett dominated, the period when Roger Waters dictated, and the brief period (one album, the moony one) when they could actually be said to be working together as a band.

For the record, all my favorite Pink Floyd songs are from the pre-Dark Side, Barrett period: “Arnold Layne”, See Emily Play and “Lucifer Sam.” This may be sacrilege, but my favorite Roger Waters project is his post-Floyd media-age musing Amused to Death. Maybe I’ve just never done the right drugs.
