"A Rock Star Bucks a Coffee Shop" is a song recorded by Neil Young and Promise of the Real.
[1][2] It refers to the lawsuit by Monsanto against Vermont due to the state's attempt at passing a GMO labeling law.
"[4][5] In a brief review of the song, Stefan Schmidt in The National Singles Round-Up also remarked that song did not hold back against critiquing Starbucks and Monsanto and suggested that Young hadn't lost his appetite for tackling political issues.
[6] Young also introduced an acoustic version of the song in Maui while performing at "OUTGROW Monsanto", a festival held to protest Monsanto's business practices in Hawaii.
[7] Moreover, the song was also featured in Young's July and October 2015 tours, for which Promise of the Real served as his backing band.
