The 'Aachener Zeitung' wrote about the world premiere at the Heimbach power station on 13.06.2008: 'The skilfully and competently mastered palette of tonal colours, stylistic devices and effects corresponds to Glanert's dramatic instinct which has reflected in seven stage works in the meantime [...]. Noctambule is clearly structured with regard to form, filled with emotion and is among the most entertaining works presented by the composers-in-residence in Heimbach in recent years. The applause of the audience was inevitable.'
