Otto Luening's Invention in twelve tones

This is another shorter flute piece by Luening, but it's different from Low speed in some ways. The first really noticeable thing is the high reverberated melody line. It has some effect on it (I guess it's just reverb) that makes it kind of disconnected even though there's always sound. It also jumps around a lot on a twelve tone scale, making it really disjunct and kind of eerie sounding (especially when the high line just starts coming in). The lower lines are kind of slow and have a bit of a wah wah feeling sometimes (was he playing around with volumes?) and the higher line is kind of ornamented and jumps around. The flute sounds out of tune somehow, like there's more than one track and they're not quite in tune with eachother. The highest notes are also quite shrill. I'm not really sure what I thought of this one.
