The band "Po 50-ce" is made up of blues and rock enthusiasts. As a band, they started their adventures with music more than 10 years ago. They named it After 50-ce because the members have been around for half a century. They meet in Kleosin near Bialystok, where they compose and practise in a professionally prepared rehearsal room owned by the bass player and the band manager. As self-taught musicians, they started to intensively develop their musical skills by attending seminars and learning from well-known musicians in order to play and create the music they love. Today they can boast about a dozen of their own songs and dozens of blues standards. They play regularly for their loyal audience at the Motopub club in Białystok. As part of their expanding repertoire, they have recently invited two young musicians to perform: Karolina Łopuck, vocalist, and Michał Górecki, keyboards, who also sings. The regular line-up of Po 50 has remained unchanged since 2012.

So far, they have presented their musical achievements at blues festivals such as Las Woda Blues, the Suwalk Blues Festival, the Lomza Blues Festival and the Palenki Blues Marathon.
