Studio engineer Liam Nolan, who has worked with artists including Amy Winehouse and Paul McCartney, talks about his route into the industry, working at Metropolis Studios, and his engineering work for Adele’s album, 25, including the single Hello – which saw him win two Grammy awards. He reveals where his Grammys are kept, and why the West London studio complex he works out of is powered largely by Genelec monitors.
