Here's how KATLA was made - recorded at the Synth & Pedal Expo London (plus sounds at the end!). Katla is a unique synth - inspired by a titanic volcano in Iceland, with a huge gritty vibey sound. It literally has volcano in it(!) And after this interview, I thought about it a lot. Because behind the scenes, I've been working on a product and so much of what Óli said here resonated with my own experiences. I was really struck by how open, candid and frank Óli was, and I think there's huge value in learning from their journey. Hope you find this interesting!

Note that there was the Hackney half marathon happening in the background with people shouting and whooping constantly throughout the chat - but Izotope RX to the rescue!
