John William Grant is an American singer, musician, and songwriter who holds both American and Icelandic citizenship. He first became known as the co-founder, lead singer, pianist, and primary songwriter for the alternative rock band the Czars. After releasing six albums from 1994 to 2006, the band split up and Grant retired for four years before starting a solo career. He returned in April 2010 with a critically acclaimed debut solo album recorded with Midlake. Queen of Denmark was Mojomagazine's Album of the Year for 2010; it was also named as one of the best ten albums of 2010 by the Guardian's music critics and writers.

Anna Brønsted is a singer, composer and visual artist originating from Copenhagen. Operating under the moniker Our Broken Garden, she has released three albums. Her most recent work, the album BLIND (2023) received widespread international recognition. Her compositional work spans far and includes compositions for choir, such as acoustic choral piece »Nattens Ende« (2021 – a collaboration with Teater S/H and composer Kirstine Fogh Vindelev e.g.) performed at Glyptotekets Festsal. At the heart of Anna’s work lies an introspect exploration of our shared blind spots, driven by a desire to unveil a profound and simple beauty, concealed beneath society's preconceived notions of success and conventional aspirations. 



Anna Brønsted has collaborated with esteemed musicians and songwriters, while also engaging in various interdisciplinary projects, collaborating with actors, theater instructors, and poets.

»Musik er lyd, som opleves med æstetisk interesse (hvilket igen vil sige et eller andet med en frivillig, intens opmærksomhed, eller lyd som er skabt med henblik derpå).«
