In March 2020, Berlin-based retro-rock band Kadavar—pioneers of modern psychedelic and stoner rock with albums like Berlin (2015)—delivered a special studio live session Vol. I in their rehearsal space in Berlin, a response to the pandemic when concerts were impossible. Their 70-minute performance, captured in high quality and released as part of The Isolation Tapes, embodied the lockdown period climax, where Christoph "Lupus" Lindemann's heavy riffs merged with Christoph "Tiger" Bartelt's drum power and Simon Bouteloup's bass lines to evoke resonance for fans online. Featuring tracks like "The Devil's Master", "Evil Forces", "Into The Wormhole", "Black Sun", and "Die Baby Die", this show highlighted their role in reviving 70s rock, turning the studio into a realm of collective groove.
