Back in January, Neil Young announced that he was working on a new concept album with Lukas and Micah Nelson, two sons of his friend and duet partner Willie. He joked that he’d name the album The Monsanto Years after the villainous corporate agriculture giant. Or at least, people thought he was joking. He may not have been. Jambase reports that Young played a secret show on Thursday night at SLO Brewing Co. in San Luis Obispo, California. He debuted his new band, which includes the two Nelson brothers, and he debuted a bunch of new songs that, according to people who were there, rail against companies like Monsanto and Starbucks (which Young railed against last fall). Their titles include “Monsanto Years,” “Seeds,” “Rock Starbucks,” and “Too Big to Fail.” They also played a generous handful of older songs. Check out a few fan-made videos below.

Serendipity strikes again! A concert so impromptu that we went with backpacks full of vegetables. #NeilYoung #magic #legend #slobrew #thankyou !! ??
