He began playing guitar at the age of 11, and during his studies at the Central Industrial School of Electrical Engineering in Bratislava, he was a member of the bands Fontána and Jolana.

[1] In 1968, Ursiny formed the New Soulmen, with Ján Lehotský on keyboards, Fedor Letňan on bass, and Peter Mráz on drums.

He composed music for Juraj Jakubisko's 1977 short film, Bubeník Červeného kríža, and Július Matula's Řeknem si to příští léto.
