The red-blooded American in me loves a box set. Who doesn’t want lots of stuff, particularly if it’s attractively packaged? But the specifics of a box set are the rub. If you’re a fan of the artist, you likely already have much of the material on the box. If you’re not, buying one is a pricey way into an artist. They also rarely hold up from end to end. There’s frequently a disc that presents the artist in process, or one that honors the later material that only diehard fans care about.
