Watch Guitar Heroes at the BBC online: Episode 4 Episode 4

This edition kicks off with big hits from the Rolling Stones and David Bowie before taking things down a notch with the acoustic picking of Michael Chapman and the Irish mysticism of Horslips. However, it's not long before the likes of Motorhead, Nazareth and straight up blues-rocker George Thorogood turn the volume right back up to 11. A spot of flamenco from Paco De Lucia and a classic track from Strat-master Eric Clapton round off the show. Filmed in the 1970s for shows including Top of the Pops, Parkinson, Rock Goes to College and The Old Grey Whistle Test, these rocking tracks will leave you wondering why pianos were ever invented.
