Is I'm in a Rock 'n' Roll Band! coming back?

What is the DNA of a great rock 'n' roll band? The series breaks this mythical beast down into its constituent parts: singer, guitarist, drummer as well as the shadowy 'other one', whose face we don't quite know but without whom the magic wouldn't happen. The evidence is examined closely in forensic studies of what makes these rock 'n' roll types tick, starting with the lead singer. Often he's the leader, sometimes the dictator, benign or otherwise. His voice is his instrument and out front there's nowhere to hide. He hires. He fires. And when it all goes wrong and the backlash begins, he will get the blame.
