His journey, however, wasn't a straight path to success.
He started his career in a recording studio in North Wales, facing financial struggles and uncertainty about his future. It was his friend and collaborator, Julian Cope, who gave him a harsh reality check: "You're unemployable in the real world. Find a way to make this work because you won't last five minutes, you'll go completely crazy."
Wrench's fortunes took a dramatic turn when a track he mixed for Caribou, "Odessa," became a global anthem in 2010. This opened doors to a new world, leading him to work in New York and experience firsthand the impact of his music. His career quickly gained momentum, with albums he worked on for artists like Jungle, FKA twigs, Glass Animals, and Caribou all hitting the charts within a month of each other in 2014.
Wrench's mixing skills have been instrumental in shaping the sounds of numerous artists, including Frank Ocean, David Byrne, Blur, and Erasure. His work has been featured on releases by Jamie xx, Sampha, Blossoms, Ezra Collective, Kelly Lee Owens, Primal Scream, and even the 1975's George Daniel.
"When I met David it was apparent straight away he was a mixing engineer and musical mind working at the highest level," says Caribou's Dan Snaith. "It was only a matter of time before the world caught on to his talents."
Wrench's journey to success wasn't without its challenges. He was discouraged from pursuing music in school, but a physics teacher, Gorwel Owen, introduced him to the world of production and encouraged him to explore his passion. This led him to create the first ever Welsh-language acid house record as Nid Madagascar in 1990.
Despite early setbacks, Wrench persevered, honing his skills by working at Bryn Derwen studios in Bangor. He found his calling in engineering, recording local bands and collaborating with Scottish songwriter Jackie Leven, which resulted in 14 albums together.
His deep immersion in the Welsh language music scene proved crucial to his development as a mixer. "I could turn on Welsh radio on any night and hear my work," he says. "This was invaluable. I could then switch to BBC Radio 1 or 6 and compare, to figure how to make my productions or mixes stand up against not just other Welsh language music, but everything."
Despite his initial doubts, Wrench's dedication, perseverance, and passion have earned him a place among the most respected figures in the music industry. His work has not only shaped the sounds of countless artists but has also served as a testament to the transformative power of music.
