Solid Sessions are Cyril Helwig and Thymen Holleman, two friends with a burning passion for music who have produced together for the past 7 years under pseudonyms like Quarck and M.U.S.E. They enjoy the perfect production partnership - Cyril is the master of percussion while Thymen's strength lies in constructing beautiful, elaborate melodies. You can clearly see both sides to the duo on their latest single Janeiro. A firm favorite with clubbers and DJs alike, Janeiro swept across the major European clubs like a wildfire.
