Ryan Adams, Olympia, Dublin

The one-time boy wonder of alternative country, for the past 11 years Ryan Adams has worked hard at cultivating a reputation for eccentricity and headstrong waywardness.

There have been drug rumours, stand-offs with the media and an endless flow of albums (including an unlikely foray into heavy metal).

He was supposed to have laid his demons to rest on last year’s Ashes and Fire. The mostly acoustic record was the best thing he’d done since 2001’s Gold. The implication was that the 36-year-old, who is married to actress Mandy Moore, had finally achieved inner peace.
