Why cover one rock classic when you can mix two – and Utah's Spirit Machines prove Tool's Sober and Zeppelin's Kashmir create a heady sonic cocktail here with their mashup, Zober.
Tool were impressed enough to shout about it on their Instagram.
The Salt lake City band consists of vocalist Pepper Rose, bassist Sergio Marticorena, guitarist Dave Crespo and drummer Michael Collins.
Zober appears as a bonus track the band's debut album Feel Again and is available from spiritmachinesband.com
