the following has been taken verbatim from Machine Head's official website, www.MachineHead1.com After two albums and more than 3 years with the band, guitarist Ahrue Luster and Machine Head have decided to amicably part ways, citing creative differences as the main reason behind the split. For those concerned, the band will still be playing all of their scheduled Summer shows and festivals overseas, and will continue on track until a new guitarist is found. Stay tuned for more details.
