I got this album on pre order and was initially quite disapointed. I thought the songs were bland and John had taken a step back from his work on Continuum. I persevered with it though and while I can't say it's as good as his last record there are some genuinely interesting tracks on here.
There is a feeling of confidence when you listen to the songs, as usual with Mayer's releases the quality of the writing remains high throughout, stand out tracks for me are Assassin - reminds me of Sting's best stuff and has a beautiful guitar solo ; Half of my Heart - not so sure about Tayor Swift's part but it's a snappy country/pop song ; Heartbreak Warfare - great groove, thoughtful lyrics and believe it or not, Crossroads - everyone seems to be slating it but I think he's done something interesting with a classic track, it's contemporary and Steve Jordan's drumming is a perfect fit as ever. I can also say, having caught one of the dates on this tour, that these songs translate very well live.
I think this is an album to invest some time in. It's not the instant classic that Continuum was but it's a genuinely well written and interesting pop record from a guy who, in my opinion, is one of the most talented songwriters of his generation.
