 "Incoherence" is Hammill's fourth (either with Van der Graaf Generator or solo) long piece of music with continuous transitions between sections which can be identified as single songs.At 41 minutes, however, it is twice as long as the earlier examples, "A Plague of Lighthouse Keepers" (1971 with Van der Graaf Generator), "Flight" (1980) and "A Headlong Stretch" (1994).Musically, the 14 sections vary widely from calm, harmonic songs to difficult and highly demanding sections, tied together by Hammill’s unusual voice, a focus on keyboards and the concept of the album
