On August 4, 2019, Dutch metal band Within Temptation who was set to perform at Byblos on August 7 pulled out of the festival in solidarity with Mashrou Leila and "in support of tolerance, freedom of speech and expression". The cancellation of the Mashrou Leila concert triggered protests and a solidarity campaign on social media. Supporters described the cancellation as a shameful and dangerous precedent. On the date of the concert, independent activists gathered to put on a show in solidarity with the band and against censorship under the banner “The Sound of Music Is Louder.” The event gathered dozens of sympathetic musicians, bands and comedians at 'The Palace' venue in Beirut's Hamra district. Over a thousand people attended the show while hundreds waited in droves at the venue's entrance in waiting. At 9pm, pubs and restaurants across the city played Mashrou' Leila songs in solidarity with the band. On August 24, 2019, Internationally renowned cellist Yo-Yo Ma played "Tayf" at the end of his Byblos festival concert as a tribute to the band.
