Given that they've spent years trawling through old recordings of Chester Bennington in order to help form their upcoming album Amends, it's no surprise that Grey Daze – Chester's first proper band – have some incredible, never-before-seen material from the late Linkin Park frontman.
Case in point: The band recently shared an awesome video of a young Chester singing along to Nirvana's Polly – and while it's not a fully-fledged cover, it's a really cool glimpse into how the star spent his days as a teen, jamming with friends to his favourite music.
