ou never really know what you're going to get with a Beck concert. The 38 year old Scientologist has recorded twelve albums over the fifteen years that he's been in the music industry, and of those it can be said that no two are alike. He's done everything from mournful acoustic ballads to postmodern sample collages while covering everything in between. His latest album, Modern Guilt, is produced by Danger Mouse and so it's heavy on the psychedelia. Whatever he plays, expect to hear things like "that song doesn't usually last three hours, but we got into a serious thing there". Beck takes over the Orpheum Theatre tonight.
