A young harpist, Imp Y Celyn from Llamedos (spelled backwards, "sod 'em all", a tribute to Llareggub in Welsh poet Dylan Thomas' "Under Milk Wood"), comes to Ankh-Morpork in hopes of becoming famous. Unable to afford the Musicians Guild fees, he and fellow unlicensed musicians Lias Bluestone (a troll percussionist) and Glod Glodsson (a dwarf hornblower) form "The Band with Rocks In", named after Lias' tuned rocks. When Imp's harp is destroyed, he acquires a guitar from a mysterious shop, unaware that it contains the awareness of a primordial music that was responsible for bringing the universe into existence. Imp takes the new name "Buddy", as "Imp Y Celyn" literally means "bud of holly", and Lias starts calling himself "Cliff".
