Thanks everyone.
The second clip is from an interesting group; The Kyteman Orchestra. Colin Benders, alias "Kyteman", is a trumpet player composer that spent way too much time locked up in his room. His roommates (mostly from the hip hop scene) egged him on to take his music outside, so he agreed to under one condition: he wanted to do it with an orchestra. (orchestra? more or less the group in the clip minus choir).
So he did, and they did it with him, and it took off! Basically he had some ideas and during the rehearsals we blessed it out as a group.
People liked it and we ended up selling out the largest venues in Holland.
A year later we thought he'd stop but he wasn't finished and that's when the choir came into it.
At every gig we also did jam's. Literally free improvisations but within the constraints of popular genres. So if, for example, a free solo ended up in a groove the strings or the brass might suddenly come up with a melody, "teach" it to the rest of the section (playing it off mic), and signal Kyteman our conductor (conductor, more like a DJ with an orchestra instead of a record player). Then we'd wait until he decided "this is the moment" then we'd play our "epic" melody, fully harmonised (free choice amongst the musicians).
In our last season we dropped the choir and did only jam sessions. Quite a feet with 15 people, and a plethora of hand signs for all 12 keys, major, minor dim, aug, dynamics, etc.
But we knew it would end, and it did. He's into modular synthesisers (he even worked a short period for Hans Zimmer).
The quintet, K.O.Brass!, is the originally the brass section from the Kyteman orchestra. We play our own music and our latest CD is also on YouTube. Here's another;
