About Us
The band Rotosphere has long been a fixture at the Blues Festival Baden (Switzerland). Led by guitarist and bandleader Nic Niedermann, they have shaped the legendary Late Night Jam Session since 2005, sharing the stage with artists such as Magic Slim, Susan Tedeschi, Coco Montoya, Justina Lee Brown, and Chicago blues harpist Matthew Skoller.
A special moment occurred in 2021 when Mark Slate took the stage: The charismatic blues and soul singer captivated the audience with his powerful voice in no time. Slate, who toured for years with the "Joe Cocker Tribute Show," embodies the raw, earthy blues. Together with Rotosphere, they deliver original compositions bursting with musical power – pure energy and a guaranteed listening pleasure!
