In 2005 Massimo and Pierce released a new album, OperettAmorale. OperretAmorale is the fifth official release by Black Sun Productions and it features Massimo and Pierce paying homage to the poetry of German poet, playwright and thinker Bertolt Brecht (1898 - 1956). As many of Brecht's lyrics explored themes of human sexuality, morality and prostitution, Brecht was an influence on both men's lives from an early age. OperettAmorale features Brecht's original work retranslated by guest musicians including Coil (contributing a version of \"A List of Wishes\", recorded by John Balance prior to his death), Lydia Lunch (providing vocals to \"The Ballad Of Sexual Dependency\") and H. R. Giger (performing \"Seeräuber-Jenny\" in addition to providing a cover image for the album).[13]
Massimo and Pierce have also collaborated with the Italian industrial music producer Mariae Nascenti in live performances and on the CDs Morituri Te Salutant and Anarcadian Night.[14]
In 2006, Black Sun Productions released the double album titled The Impossibility of Silence, featuring Massimo and Pierce and guest artists such as Lydia Lunch, Val Denham, Sudden Infant and Sonne Hagal. Throughout the year the collective played a number of live performances including \"Darkness Is Enlightening\" at Paradiso, Amsterdam, on a multiple bill with Psychic TV, Lydia Lunch and Val Denham.
