The latest soundtrack album from Hollywood roots-music maven T Bone Burnett pairs original tunes sung by “Crazy Heart” stars Jeff Bridges and Colin Farrell with classic country cuts by such artists as Buck Owens (“Hello Trouble”), the Louvin Brothers (“My Baby’s Gone”) and Townes Van Zandt (“If I Need You”). So far, so typical. The surprise on the set is how well the new music holds up against the vintage material. “Fallin’ & Flyin’ ” finds Bridges and Farrell joining forces for an effortlessly tuneful honky-tonk gem, while Bridges unloads a bit of plain-talking, beer-hall existentialism (“I used to be somebody, but now I am somebody else”) during “Somebody Else.” Alt-country artist Ryan Bingham contributes a pair of tracks, one of which (“The Weary Kind [Theme From ‘Crazy Heart’]”) recently won a Golden Globe for best original song.
