There's an in-depth interview with the lovely Wolf Alice over on DIY:
“Everything else is practice, in a way,” agrees Ellie. “I think those early years are so important. When we look back to our first few tours, when it was playing to ten people in Warrington, that’s really special to me.” What’s led them here, though, is a sense of belief. Even when members were coming and going, when Theo wasn’t taking to his chosen instrument and when Joel was playing live drums for the first time, Wolf Alice only happened because every member realised it was going somewhere.
