The downside to being a prolific singer-songwriter? Not every record is going to hit the mark. But with Prisoners, Adams has released his best, most fully-formed and emotionally vulnerable album in years. Before that, Adams kept himself busy by launching everything from a metal concept album to a record of Taylor Swift covers—not to mention finally coming to terms with the incessant requests for Bryan Adams's "Summer of '69". Don't miss him, though; he always delivers live.
