Sign of Four Denmark Country Club

Sign of Four is a contemporary string quartet formed in 2022 by Shenzo Gregorio, Daniel

Drieberg, Mardae Selepak, and Jude Iddison. Their innovative and intricate original

compositions and interpretations explore the sonic possibilities of combining violins, guitars,

mandolin, and octave viola with lush vocal harmonies. Sign of Four draw from classical,

folk, jazz, and rock foundations in a seamless flow of musical creativity, taking audiences on

an exhilarating, and inspiring musical journey—from Vivaldi to ACDC, Reinhardt,

Piazzolla, Sting, Bowie and beyond.

Shenzo Gregorio brings decades of musical experience and innovation through his cross-

genre improvisational and multi-instrumental skills. A master of the violin and guitar,

Shenzo also showcases his virtuosic, idiosyncratic creations on the octave viola.

Daniel Drieberg is a prize winning WAAPA jazz graduate with exquisite multi-

instrumentalist skills on violin, mandolin, and vocals. He combines these with an infectious

energy that enlivens his musical collaborators and delights audiences.

Mardae Selepak is a vibrant young classical guitar maestro whose musicality transcends

genres. His sublime compositions and vocals bring an added grace and depth to Sign of

Four’s arrangements and performances.

Jude Iddison is currently undertaking a PhD in violin improvisation at WAAPA. Her lifelong

fascination and irresistible curiosity with a diverse range of musical styles is highlighted in

her sensitive, versatile, and expansive violin playing and eclectic compositions.
