Michael Franti: Back and Forth, Dan Hegarty The Alternative, 10.00pm RTÉ 2fm.

Michael Franti was the voice behind Television The Drug Of The Nation, the track that U2 popularised across the world as the intro to their highly-flammable, sophisticated Zoo TV tour. Michael Franti's career has had many twists and turns, from the early days of The Beatnigs, to Disposable Heroes Of Hiphoprisy, through to Spearhead. Dan picks the best from his musical trajectory in this week's Back and Forth.
