On Friday September 26th there was a double concert in Amager Bio.
The second band was Otis Grand and the Big Blues Band. Another band I'm afraid I'd never heard of before either, and another concert I'll never forget !! - Have a look at their web-site as well.
At the end of the performance, they invited Mike Andersen Band back on stage. The now 12 people on stage, played at full speed for 15 minutes, and Mike Andersen even broke a string.
