Astubbornheart has 5 Thornhill concerts.

After the band – comprising of Jacob Charlton (vocals), Ethan McCann (guitar), Ben Maida (drums), Nick Sjogren (bass) and Matt Van Duppen (guitar) – graduated from high school, Thornhill played their first show with Hellions. As a collective, they were only three months old at the time, but they grew rapidly from there, finding themselves on triple j rotation and scoring Unearthed Feature Artist in November 2017.
