Grails are a Post-Rock,Psychedelic,Progressive instrumental band from Portland Oregon. This is collection of experimental music originally released on an EP and a split record with another band. Vol. 6 (Side 4) is unreleased. Its a nice collection of music, most pieces are in the 4 minute range with acoustic and electric guitar,piano,electronics,and some found-sounds. The music ranges from Psychedelic to progressive to electronic.”Ice Station Zebra” sounds almost like New Age music. There is a Black Tar Prophecies Vol. 1,2,&3 that I would like to get if I can find it. They are an interesting band and I would like to hear more of their music
