Post Malone is on top of the world right, with his new 21 Savage collaboration “Rockstar” debuting at number two on the Billboard 100 this week.
During a show in Silver Spring, Maryland earlier this month, Post decided to perform a cover of Green Day’s 1994 hit “Basket Case” from the band’s Dookie album. Post sat on a stool and sang the song while playing an acoustic guitar.
Even Green Day frontman Billie Joe Armstrong gave it a cosign.
