I have recently finished listening to Petterson's Symphony No. 8 and I am listening to Symphony No. 10 right now. I do not understand why this composer is so under recorded? Is it because his works are dark and moody sounding? His works definitely have a tonal center to them. I find Symhony No. 8 of Pettersson's to definitely be one of my favorite symphonies; that is No. 8 in the middle half of the 20th Century. I need to listen to every symphony of his. Does anyone else enjoy listening to Pettersson's works? If so which ones?
