My problem with Pearl Jam is that they don't demonstrate much musical and vocal diversity--they seem to exploit the same kind of brooding guitars and vocals throughout all their hits--though sometimes their poignancy is undeniable. While I like the sound, beyond Pearl Jam's lyrics (and even then...), I don't necessarily find them particularly artistic.
Pearl Jam just has nothing on Nirvana, imo.
You'll get no argument from me on that, couldn't agree more. I know he gets a lot of love, but Grohl is truly an amazing talent that is worthy of every bit of it.
