Do people really talk about Wilco as a country band anymore? I know they used to be lumped into the whole alt-country thing, but it feels like — nearly three decades into their tenure, and especially after experimental triumphs like 2002’s Yankee Hotel Foxtrot and 2004’s A Ghost Is Born — they’re viewed more like a rootsy indie-rock jam band or something. I rarely see the “C word” deployed to describe them anymore, though they of course do make twangy songs from time to time. Maybe that has something to do with the band’s decision to, at this late date, record a country double LP.
