Everyone in the world who is remotely interested in music should own this CD set. Everyone. Each and every person should be forced to hand over the cash so Mr. Brotzmann and his band can continue their good work.
Mind you, you probably won't like it much at first - but that's good, because you can listen to it again and again and again until you do. Basically, you shouldn't be allowed to buy another piece of music until you start enjoying this one.
A copy of this music should ship with every i-gadget in a format where it can't, ever, be deleted. It should be piped through every venue where muzak is available. Entire radio stations should switch over to simply playing these five discs - back to back - over and over. The theme music for every soap opera should start with the music on CD 4.
The opening CD should become the national anthem for all nations. All other national anthems should be consigned to the dustbin of time. Also, alarm clocks should stop with the "beep beep beep" and change over to the opening bars of CD 1 (trust me, it'll wake you up much faster). That way you're awake, you're a proud citizen, and also a music lover.
Wars would be averted. People would suddenly get along better. We'd enter an era of nirvana, of caring, peace, and tranquility.
Once you're into this one, buy all the other Brotzmann discs. When you're done with them (it'll take several years) you won't even want to change to something else.
You should be able to get this on prescription. Do it!
