Each to their own, and Tangerine Dream's audience reaches far far far more people than just "old men".
In any case, I'm really glad that the whole "collaboration album" didn't turn out to be just mere rumors or unrealized ideas and that he's actually working with greats such as Tangerine Dream (or rather, did work, RIP Edgar Froese) and other popular electronic artists (like Massive Attack). Then again, where's Daft Punk?
And on that note, a project like this would have been totally unheard of 10 years ago, when JMJ was still more of a "pariah" of the (electronic) music community. Good to see that he's earned more respect from his fellow musicians (and other people) in the mean time.
Even then, a full unedited concert video of the Paris La Defense concert is still the Holy Grail of JMJ releases that they should just get around to making and releasing on DVD or BluRay (even if the video quality wouldn't be up to the BR standards).
