The Simon Bolivar Youth Orchestra of Venezuela, which caused a sensation at last year's Proms, is the product of an extraordinary music education system that has been running for more than 30 years. Children as young as two get intensive music lessons designed to steer them away from the dangers of the street.

With Scotland now trying its own version of the scheme, Alan Yentob investigates the phenomenon and meets its most successful graduate, 27-year-old conductor Gustavo Dudamel, who next year becomes music director of the LA Philharmonic.

Rock doc Heavy Metal in Baghdad follows the struggles of Iraq's one and only metal band, Acrassicauda, and tells its own story about the horror of daily life in the war-torn city.

Following the documentary's limited cinema release Imagine presents an edited down version of that film, then picks up the story as the four band members have fled Iraq and are attempting to re-form their band in the West. Lost in a nightmare of bureaucracy, the four young musicians hold onto their dream, which is simply to play their music.
