Johannisnacht Mainz - Dance the night away! (Wiesbaden-Mainz)
My fav local band, JamminCool, will have its usual gig on Monday, the 27th of June, from 19:00 at the Bischofsplatz (near Karstadt).
If you're interested, we could meet at one place and go there together as it'll definitely be crowded with its fans.
For those who haven't heard of JamminCool, check it out. I'm sure you'll have a blast!
