In a moment of punk synergy, Hayley Williams joined young rockers the Linda Lindas for a performance of their breakout smash “Racist, Sexist Boy” at London’s O2 Academy Islington on Thursday night. Williams has made a lot of music over the years — both as the front-woman of Paramore and on her own. Similarly, when the Linda Linda’s went viral in Covid-era 2021 for performing “Racist, Sexist Boy” at their local library, the four girls were between the ages of about 10 and 16 years old. To make matters cooler, per Stereogum, two of the members, Mila de la Garza and Lucia de la Garza, are actually daughters of record producer Carlos de la Garza, who worked on some of Paramore’s more recent albums. So, it’s no wonder that Williams seemed to be having the time of her life with them.
