The inception of the band rose in the head of the harpsichord player Filip who felt that his love for baroco music could be well combined with his enthusiasm for jazz. He contacted his old childhood friend, who in a meanwhile entered both classical and jazz career - the cello player Jan. Adding another friends guitarist and composer Mirek and violinist Nina, the new band Transitus Irregularis was born in winter 2009. Together they create a refreshing mixture of unconventionally combined music styles from classical to modern and spread their joy and love for music to the audience.
