Known for his performances and production work with a number of artists and his collaborations with his brother, Oscar-winning composer Atticus Ross, on a number of soundtracks, Leopold Ross was an English musician and producer hailing from London, U.K. His career began early at the age of 15 with the rock band No Jahoda, signing with Sony imprint S2 Records in the late '90s. The group put out a self-titled EP in 1998 and one album, Jahoda Witness, in 1999. Eventually Nojahoda disbanded, and Ross continued to further pursue musical outlets with a number of projects. He went on to join his brother Atticus, Bad Religion guitarist Brett Gurewitz, and Dillinger Escape Plan vocalist Greg Puciato in the erstwhile electronic hardcore project Error. They put out a self-titled EP via Epitaph Records in 2004 that received widespread critical acclaim. The project eventually came to an end, and Leopold went on to compose one of his first scores for the U.S. crime drama, Touching Evil. Ross went on to help produce and engineer a whole host of artists such as the Transplants, Grace Jones, Bad Religion, Korn, and the Dillinger Escape Plan. In 2009, he contributed writing and production to the score for the Hughes Brothers’ movie The Book of Eli alongside Atticus and Claudia Sarne. Later that year, he returned to the stage as touring bass guitarist for English electronic band the Big Pink on their international tour. In the following years, he formed the indie rock ensemble IO Echo with Ioanna Gika. The band put out their debut single, "While You Were Sleeping," on California-based independent label Iamsound Records in 2010 and followed it up with a self-titled EP in 2012. In 2011, Ross and the band contributed a score to the short video installation piece Rebel by Harmony Korine and James Franco. Ross remained with the band, which put out their first full-length, Ministry of Love, in 2013, followed by their second EP, I’ve Been Vaping Your Tears, in 2014. In the late 2000s, he worked on a number of scores, most notably with his brother and Claudia Sarne on such films such as Broken City, Blackhat, and Triple 9. In 2016, Ross and Atticus collaborated on U.K. electronic artist Bobby Krlic (also known as the Haxan Cloak) on Steve Hoover's documentary film Almost Holy. Ross returned with IO Echo the same year with the single “Crossing Over,” a collaboration with L.A.-based composer and producer Lawless. ~ Rob Wacey, Rovi
