In hard, pandemic times, solidarity is paramount. The world that found us with the arrival of the pandemic had no mercy. The concert industry has felt it particularly strongly. Not all clubs, organizations or festivals came out of this uneven battle unscathed. However, the common fight for survival showed what a strong and wonderful community we are. To celebrate this unusual sense of unity, AAF, Undertone and Klub Pogłos together prepared a line-up for the fourth day of the festival in Warsaw. Only Polish bands. From post-punk, sludge and noise to black metal. There will appear: mathcore trio from Olsztyn Krzta, a band playing a mix of noise, grind, jazz and sludge – Dule Tree, post-hardcore Black and a trio fond of noisy and harsh sound – Próchno.
