As far as a B-Sides/rarities comp goes, this isn't the seasonal marketing scam you might expect. In fact, there's enough decent material on Sawdust to exempt Brandon Flowers and his Vegas boys from cynical gap-filler accusations.
Hot Fuss leftover Leave The Bourbon On The Shelf is a curiously strong sequel to Jenny Was A Friend Of Mine, while All The Pretty Faces, with its big, galloping rock guitar, would have injected some needed levity into the dramatically overwrought Sam's Town. Kenny Rogers cover Ruby, Don't Take Your Love To Town shows Flowers capable of dialling down his pomp, and the Lou Reed collab Tranquilize grows with each listen.
However, there are a few "rarities" best kept in the treasure chest. For instance, the U2-thieving Move Away is shameful, and the Killers' take on Shadowplay will make pale-skin Joy Division fans turn green.
