Live music review: Bill Callahan

Bill Callahan shuffled off his old alias, Smog, a few years back. Since then, his profile has shot up on the back of three perfectly realised concept albums, culminating with last year’s Dream River.
The switch has also corresponded with Callahan revealing a barer persona, both on record and on stage. In the Olympia, he and his majestic band are in wondrous form, but it’s Callahan’s raw intensity that is to the fore.
