JAMundo may have been paused for a while but a lot is happening behind the scenes, we are becoming a foundation and special events are coming up. At the same time there is also sad news. Our loyal host Dra ended up in a sad situation now that his mother is seriously ill in Mali. We are going to help him to travel to his motherland, are you helping?



After three incredible years with lots of jam sessions and connections we made on stage, we are forced to temporarily pause this world oriented concept of JAMundo. Unfortunately, the evenings of JAMundo are not cost-effective for the hospitality industry in the heart of Groningen.

Unfortunately, we will not be able to continue these evenings without the support of the municipality funding. We are currently working behind close doors with the crew members of JAMundo and those involved to re-establish this concept in a different/better and improved way.
