#modern poetry

I've been reading a lot of poetry lately and I'm looking for something new. I've already gone through the classics, so I'm looking for something a bit more modern. Can anyone recommend a good poet or collection that's worth checking out? I'm open to anything, as long as it's well-written and thought-provoking. I've been thinking about this a lot and I'd love to hear some suggestions from people who actually know what they're talking about.
