In 2021, with this album, the band was nominated for the FRYDERYKI 2021 Award in the Debut in Jazz category and was awarded the JAZZ OSCAR Grand Prix Jazz Melomani 2020 in the New Hope category.

An excellent album – mature, uncompromising, debunking myths, breaking conventions. And in a sense, it is a breakthrough – I believe that this proposal will shake up our jazz backyard
