The title is quintessentially Stephen Malkmus – a conflation of two slang terms, one dating back to the hazed-out '60s, the other a vulgar remnant of modernity – and, as it happens, Wig Out at Jagbags also sounds quintessentially Malkmusian. It's elastic guitar rock constructed partially out of cannabis guitar jams and partially out of punk rock squalls, both sides distinguished by wry melodicism and dexterous wordplay, not to mention Malkmus' lingering tendency to hide his accessible inclinations under sheets of six-strings. On 2011's Mirror Traffic, producer Beck prevented the Jicks from taking detours, but here the band is producing on its own, assisted by Remko Schouten, so they're free to follow wherever their whims may take them.
