I actually haven't minded their last 2 albums. Not near the old stuff but I can listen to it
Uplifter wasn't that bad (wasn't that good either...) and I still listen to a few songs off of that album. Universal Pulse, however, didn't do it for me. You can tell all of the creativity has been sapped from their bodies.
That said, I've seen 311 three times and each time was amazing. Plus with albums like Evolver, Transistor, Soundsystem, Grassroots, and the other oldies - they will be one of my favorite bands.
