After releasing a pair of albums last year, Neil Young is already back at work on new music, this time with Willie Nelson's sons.

Rolling Stone reports that Young is recording an album with Willie's sons Lukas and Micah.

Young jokingly said that he's calling it The Monsanto Years, a reference to the agriculture corporation that Young has protested against in the past. Young played with Lukas and Micah at Farm Aid last year.

"It's an upbeat review of the situation," he told Rolling Stone of the decision.

In 2014, Young released A Letter Home -- which consists of covers of classic songs byBruce Springsteen, Bob Dylan, Willie Nelson, Gordon Lightfoot and others -- and Storytone.

The LPs are his 34th and 35th studio releases of his career.
