It's not uncommon for an artist, even one as original as Feist, to perform a cover or two in an encore. During her sold-out concert at London's Royal Albert Hall on Sunday (March 25), the Canadian indie darling did one better and brought out her opening act, M. Ward, no stranger to male-female vocals through his work with She & Him, to sing the Jesus and Mary Chain's 'Sometimes Always.' The song, a duet with Mazzy Star's Hope Sandoval, originally appeared on 1994's 'Stoned & Dethroned.'

Feist and M. Ward are wrapping up their European tour tonight (May 27), but after a few deserved weeks off, both acts will headline tours. Feist will trek through across America and Canada before heading back to Europe in August, hitting many big festivals along the way. M. Ward will be playing clubs and theaters through the end of May in support of his album 'A Wasteland Companion,' which will be released on April 10.

As far as indie superstar encore covers go, we rate this one pretty high. But the reigning champion remains last summer's Neko Case / My Morning Jacket tour, where they would sing anything from 'Stop Draggin' My Heart Around' by Tom Petty and Stevie Nicks to 'Islands in the Stream' by Kenny Rogers and Dolly Parton.
