Wszystko Będzie Dobrze
Music and comedy trio, consisting of Maciej Kaczyński, Maciej Sosnowski and Grzegorz Uzdański. They write mini-stories, scripts and sketches and record music (although actually they've only recorded one album, but it was about the universe). They perform live in Warsaw comedy club Resort Komedii and Klub Komiediowy with an ever-changing programme of sketches and songs. They have their own YouTube channel and they still hope it will become really popular. This hasn't happened yet, though.
