Our Dance Crew. Clem, Pat, and Julie have been dancing for many years, sharing a love for movement, music, and community. What started as a passion in Leederville has grown into something truly special. Modern Roc now runs three weekly classes across Perth, welcoming dancers of all experience levels. Whether you're brand new or a seasoned dancer, our goal is to create a relaxed, social space where everyone can enjoy the magic of modern jive.
