Smoke Over Warsaw is a concert enables you to see the legendary Bongzilla band from USA and with them some polish supports like Belzebong and Black Smoke. Bongzilla is a sludgy, narcotic monstrum that has been walking this earth since 1995. BelzebonG on the other hand needs no introduction for any polish fans, it is a stoner/doom rock with devil and the bong. And Black Smoke - Wroclaw's sludge/doom crew, worth checking out.
