New series 1/4. A decade on from the releases of Massive Attack's Protection, Portishead's Dummy and Tricky's Maxinquaye, a reassessment of the influence of these seminal albums produced during an inspired flourish in inner-city Bristol's pop history. The quest to define a so-called Bristol sound includes music by Pigbag, Rip, Rig and Panic, Maximum Joy and the Pop Group. The series kicks off with a look at the scene's pioneer days of soul, funk, punk and reggae. Producer Simon Poole

Way Out West - the Bristol Underground 10.00pm R2
Bristol wasn't known for a thriving music scene until ten years ago when Massive Attack, Tricky and Portishead all emerged from the city with albums that have stood the test of time. This four-parter goes back to the roots of the Bristol scene to examine how a series of bands cooked up what became known as trip-hop from a varied list of ingredients that included reggae, jazz and hip-hop. This opener goes back to the 80s when the Pop Group and Pigbag were local heroes. (Geoff Ellis)
