Learning all over again

Today on the walk home through the beautiful sunshine in London- Manor House to be precise- I almost collided with a group of young guys- think Turkish in origin- doing what I can only describe as another twisted version of Hip Hop all acapella and I think it was just to blow off steam rather than a serious thing but it was heavy. Nothing truly out of the ordinary but another surprising layer of this ridiculous city and although my brain is a bit vaccant after heat exposure I'm now on the hunt to find out if this is a movement or just a group of bored kids hanging and just messing about. Also will check out Turkish Hip Hop in general in case I'm just a few steps behind. More soon and comments, suggestions, warnings welcome. Peace and loves. Nana
