I have seen Jack White, Alt-J and Zaz in Forest National and I must say I prefer other venues SO MUCH more.
First of all, getting there. Forest National has a dedicated parking (not guarded) in the middle of nowhere, from which you can take the tram to the venue. Problem is getting back. The tram line connecting the two places operates every 15 minutes during the night (when the concerts end) and the tram gets packed immediately. Last time I had to wait for the third one and I only chose to wait because I was not sure I would find the parking otherwise.
Second option is parking houses nearby. On my second time there (Alt-J) the parking house on Rue des Abesses was open and available, the last time (Zaz) it was closed and I had to find a parking in the packed streets around. Really doesn't make any sense.
The venue itself is BIG, with two flights of seating and a big standing place in the middle. Too bad that there are only two sets of toilets for the whole ground floor and the bars get packed soon, too.
The sound quality isn't the best and it doesn't depend on where are you at in the building. I really prefer the other venues, that might not have such a capacity, but are genuinely more suitable for musical shows. read more
