Plack comes from a family of classical musicians. He studied classical violin, piano, guitar, and voice from a young age. He also enjoyed the improvisations on his father's jazz records and eventually turned toward the Australian landscape for inspiration. Plack picked up the didgeridoo in the early 1990s and immediately started his recording career with Johnny "White Ant" Soames, after being inspired by hearing a world beat song by Peter Gabriel and Youssou N'Dour. He has also collaborated with David Gulpilil and other Aboriginal musicians of Arnhem Land, Northern Territory.
Plack has often performed and recorded under the name "Nomad," and in 1995, he was nominated for an ARIA Music Award (Australian Grammy) for Best Album in the World Music category. He has participated in a number of cross-cultural music projects, including several recordings of meditation music with NY Times best-selling philosopher Deepak Chopra, including A Gift of Love (1998), which consists of translations of the poems of Rumi. He has also written and produced several Guided meditation albums with Deepak Chopra, and has composed a contemporary Opera entitled "CoCo De Mer."
Plack wrote and produced the single "With You" which reached Number 2 on the Billboard Dance charts and won the 2001 ASCAP Rhythm and Soul Music Award.
Plack resides in Los Angeles and continues to compose and produce albums, film and television scores under his new label, Play It By Ear Music, alongside his life coaching practice.
