Born from the creative mind of Ethiopian-Swedish bass guitarist and composer Cassius Lambert, BITOI, or ‘Bass Is The Original Instrument,’ is a unique sonic experience that blends the human voice with the electric bass, weaving in bird phonetics, vocal percussion, and wind tones. This unique blend creates a distinct, potent sound, seamlessly uniting vulnerability with strength and infusing the human element with robustness.

In 2023, they made waves in the music industry with a highly anticipated project. They delivered an unforgettable performance at Malmöfestivalen in August, were praised by Crack Magazine for their Intonal Festival performance, by the end of the same year BITOI was released, they had a mind-blowing performance at Le Guess Who? 2023 festival in Utrecht gaining an incredible positive feedback.

BITOI’s live shows create a deep emotional connection with the audience, and they’ve recently released their debut EP, ‘-O-‘, which beautifully balances fragility and power.
