Sleep Good took it upon himself to reimagine an angsty Nirvana classic as an upbeat, pop-punk jam–all thanks to exchanging minor chords for major ones. The Austin, Texas artist, who crafts ‘summertime dream pop’ according to his Bandcamp page, titled his re-work “Nirvirna – ‘Teen Sprite.'” It’s a certified pre-summer bop to shake the winter blues.
