Query: Their greatest.

It's a shame they're not the same way now, as I wish they would do similar material. The Pearl Jam today is no longer Pearl Jam; it's a wannabe folk band that likes to collaborate with other artists. The Pearl Jam back in 91/92, however, were an excellent hard rock band which essentially opened the scene for 90s alternative rock (and alternative metal). What was so great about the album? Well, each track told a story. Not in a spoken-word way, in a "Van Morrison way" with guitar riffs and deft bass work in the background. Their live shows were pretty cool, too.(At this point, they're all pretty old, but they could always make a comeback!) You won't think I'm being absurd by saying that THIS album is to rock music what The Godfather is to motion pictures.
