The biggest twins in pop are returning to where it all began with High School, a book chronicling the acid, raves, girlfriends and guitars that shaped their teenage years

There are plenty of early 90s touchstones that pepper Tegan and Sara’s elegant and evocative memoir High School, which tells the story of their teenage years in Calgary, Canada. There are Kurt Cobain shrines, mosh pits at Green Day shows, teenagers playing Street Fighter in arcades. The most 90s of all, however, is how much time the twins spend on the telephone. Friendships, love affairs and messy personal sagas all take place over a shared landline.

Today, Tegan and Sara Quin are calling separately from their homes close to each other in Vancouver to explain why they have decided to revisit their adolescence in great, probing detail. To listen to them chatting away down the line is apt. It brings the book so vividly to life that I almost find myself twirling an imaginary cord around my finger.
