While listening to radio in the car between villages I happened upon a Polish band which, while I couldn't understand the words, reminded me of the music of Sex, Drugs and Rock-n-Roll (before the BeeGees, obviously!). The band is called Dżem (prounced "Jam" — as in “to jam”).
Started in 1973, Dżem was lead by singer Ryszard Riedel -- who, as countless rock heroes, died of complications from opiate abuse. (Though he was pretty much older than 27 and prolly shuda known better.)
When I was in Poznań I enjoyed a street musician who, according to my friends, was playing Dżem. (Yes, yes! Videos should be in landscape, you idiot!)
