Neil Young/Pegi Young

The eternal enfant savant Neil Young calls Chrome Dreams II "a form based on some of my original recordings, with a large variety of songs, rather than one specific type of song," which is true even if no one knows what the hell that means. After the all-too-literal eco-mess of Greendale and the once-necessary, now-fruitless fight songs of Living With War, Young may be better off not meaning too much, even as he dips into his infinitely inscrutable archives for long-rumored, eighteen-minute guitar and horn epics, dorky jokes, country fluff and Crazy Horse smackdowns. His current tour features wife Pegi as an opener and then acoustic and full-out electric sets from the impetuous genius they don't call Shakey for nothing.
