There are many good anecdotes about Tangerine Dream, but this is one of the few scandals.
Together with Nico - the charismatic chanteuse of Velvet Underground fame - they played a now legendary concert, but consequentially it got them a lot of positive publicity.
According to the TD disliking journalist, Steve Lake, who wrote an article about the event ("Rock Goes To Church"), french national newspapers had written about a bomb threat rumour! The bomb should detonate at 8.00 pm, and the band's manager, called Andy, told Steve Lake not to mention it for the band, as "they are particular paranoid about being blown up"!
Of obvious reasons, that didn't happen, nevertheless another problem occured:
The capacity of the Notre-Dame cathedral was only 2000. Instead, the managers succeeded in letting 5300 people in. And with no freedom of movement - and the toilet facilities ditto, the result was people urinating up against walls and columns!
That, combined with the fact, that alcohol was drunk, pot was smoken and other types of unchristian behaviour was displayed, Pope Paul VI decided to indefinetely ban Tangerine Dream from playing at catholic churches.
Tangerine Dream had no influence on the controversy, but it did in no way harm their reputation, and they played even more cathedral concerts in England, the following year.
For those people who weren't stuck inside the cathedral, one could have a listen, as the show was broadcast on radio.
This broadcast provided the background to the famous Live! Improvised! bootleg, which this Tree release is based upon.
The sound quality is on par with an official live album and the music is lovely, smouldering, disturbing, psychedelic 70's electronica.
What I like about it, is that the sequencers are used moderately and with skill. They could have used them all over, but a good thing shouldn't be overdone. The gothic architecture is certainly an inspiration to music. The courses of ambience are lenghty, and when the sequencing kicks in, they sure have built up a wonderful climax!
