Some time ago but still listenable:
The german Webradio-Station www.radiomelodic.de
has aired Machinae Supremacy 2 times so far. At least in the second part they present the style MaSu does and gives a good over and review for the style of the music.
Even if you don't understand german the radio-station is still really good to tune in and listen to. They broadcast one show of 2hour length every week / 2 weeks. The Soundquality is quiet good for a streamed radio-station.
