The 1st wave industrial bands that refused to branch out, change their sound, or change their sensibilities are what is wrong with the very nature of industrial music. Let your music change, don't get tied down by the purity of industrial as a performance art or music genre. I and others have a lot more respect for the classic era industrial bands that did branch out and find the sound of classic industrial too tiring. Cabaret Voltaire, Coil, and the Neue Deutsche Welle scene in retrospect are far more memorable than anything by Throbbing Gristle, Carter Tutti, or any other such interchangeable 1st wave performance group.
