The award-winning Canadian-Czech singer and composer Lenka Lichtenberg was going through her mother's effects in 2016 in Prague when she made a startling discovery. She found two small notebooks that belonged to her artist grandmother, Anna Hana Friesova (1901-1987). Inside each notebook, small enough to fit into a back pocket, were poems written while she was imprisoned in the Terazin (Theresienstadt) concentration camp during WWII.

Lichtenberg, who was born in Prague but settled in Canada in the 1980s, decided to record the poems for "a music project spanning eight decades and three generations". The result is Thieves Of Dreams: Songs Of Theresienstadt's Secret Poetess, Anna Hana Friesova 1901-1987 (Six Degrees), a haunting set of musical gems.
