The Music Biz 9.40pm BBC2
If anyone still has any illusions that the music industry might offer a glamorous lifestyle after watching the first five programmes, prepare to lose them now. Tonight's edition examines the most demanding of all rock 'n' roll rituals: the tour. "The only reason I go on the road is to get on stage," says Jon Bon Jovi. "The rest stinks. They pay me for the other 22 hours." The Music Biz joins US metal band Metallica as they prepare for a show at Milton Keynes Bowl, the final night of a two-year tour. And while the band are on stage, piles of unofficial merchandise and touted tickets are sold outside the gates.
