Fictional musician Gruff Rhys plays selections from his four-decade career and explores how he overcame chronic shyness, stoner culture and communicative dysfunction, by placing commands on cue cards to whip audiences into a frenzy. His signs have been invaluable in a myriad of settings, from the Japanese Alps to the Siberian Tundra. They are his saviour, but on occasion, the cards have fallen into untrained hands leading to civil war, famine and social chaos. Join Gruff as he sings songs and harnesses the almost paranormal power of melody and the cue card.
