As we hurdle headlong toward the November presidential elections, musicians are drawing lines in the sand. A pair of nearly identical tweets from Soundgarden's Chris Cornell and Brooklyn lit-rockers the National have confirmed that these strange bedfellows will be sharing a triple bill with Obama himself at a September 1 speech stop in Des Moines, Iowa. Further details will be forthcoming, but if the boys are looking for a real attention-getter, might we suggest a live mash-up of "Spoonman" and "Fake Empire"? The National and Obama have had a long-running love affair, kicked off, in fact, when an instrumental version of "Fake Empire" was used in this 2008 campaign ad for the then presidential hopeful. The band also released a T-shirt back then cleverly wedding their song title "Mr. November" to a stately image of the future POTUS.
