If you want to experience a spiritual rollercoaster, be sure to head to Warsaw's Hydrozagadka on May 12. You will be led through your own ritual by Big Brave and Kee Avil.

In Big Brave there are no easy solutions, no pleasant themes to hum, there is only purification. When they drop post-metal riffs on the listener, it can feel like a healing, and that's just the beginning of the attraction. Just as often, the group also reaches for droning trances that affect the listener like a mantra. Enter this peculiar world.

Kee Avil is theoretically doing pop, but don't expect anything cute. In her case, pretty songs are extremely glitchy, morbid melodies enter the head and wreak havoc, and the music has plenty of layers to explore. Isn't that beautiful?
