the composer's website: "About a year ago, I was persuaded to agree to interviews in the lead-up to the opening of the new Cobar Sound Chapel. I have pushed myself to go along with media requests I was very uncomfortable with. This has led me to a state of total mental exhaustion. I therefore regret to say there will be no more interviews." In the 2012/13 season, Lentz was in residence at the Internationales Künstlerhaus Villa Concordia in Bamberg, Germany and collaborated with Jonathan Nott and the Bamberger Symphoniker. In January 2015, a new orchestral work, Jerusalem (after Blake), taking its inspiration from Jerusalem by William Blake, was premiered by the Luxembourg Philharmonic Orchestra. In May 2015, a portrait concert of Lentz's music by the Munich Chamber Orchestra at the Pinakothek der Moderne included the world premiere of the definitive version of Birrung (1997-2014) for 11 strings. In November 2016, the final version of Jerusalem was premiered at Wien Modern. In April 2022, a major new sound art project, the Cobar Sound Chapel, opened in Cobar in Outback New South Wales. It is a purpose-built venue to permanently house the 4-channel projection of Lentz's digital string quartet, the 372-minute / 24 hour composition String Quartet(s) (2000-2022), as well as the venue for a new annual String Quartet Festival Weekend. The Cobar Sound Chapel was designed by Pritzker Prize-winning Australian architect Glenn Murcutt in collaboration with the composer, with its architecture reflecting rhythmic and structural patterns found in String Quartet(s). A new violin concerto, "...to beam in distant heavens...", is due to be premiered by German soloist Arabella Steinbacher with the Sydney Symphony Orchestra at the Sydney Opera House in April 2023. Lentz's music is published by Universal Edition in Vienna. Music Lentz's music expresses his fascination with astronomy as well as his love of the Australian Outback and Aboriginal art (in particular the works of Kathleen Petyarre), and reflects his spiritual and existential beliefs, questions and doubts. The Vale of Glamorgan Festival (UK), where Lentz was a featured composer in 2006, introduced his music as "...an awestruck and almost fearful response to the beauties and mysteries of the universe; a massive, personal creative undertaking from which this intense, almost obsessive composer is painstakingly extracting concert works...a unique voice whose music is genuinely moving despite its brittle austerity and unearthliness, and captures some of the most evocative silences imaginable."
