I have already mentioned that Rennes has its annual music festival “Les Transmusicales” just after IEEE WIFS, from 7-10 December.
Be careful: Hotels downtown are expected to be crowded starting from Thursday 7th.
This gives WIFS attendees the opportunity to attend some concerts. The program of the festival can be found here lestrans.com
There is also the ‘off’ festival in bars downtown: barentrans.com
Don’t be surprised to know none of music bands in the program. It is the spirit of the festival: discovery of new but promising bands.
