Out of the cocaine-fuelled, rock''n''roll debauchery of the 1970s came an iconic collaboration between an influential rocker and a visionary filmmaker. From The Last Waltz to The Wolf of Wall Street and The Irishman , the creative legacy of Robbie Robertson and Martin Scorcese has spanned decades. Filled with high octane exploits, bacchanalian parties and untold amounts of debauchery, this is the intimate and unvarnished behind-the-scenes story of a partnership that has shaped American culture like no other. PRAISE FOR TESTIMONY ''A book of memories and wonders, a personal testament of a magical time in American music from someone who was there, at the center of it all . . . Robbie brings you along with him, keeps you right by his side first to last, just the way his songs do, drawing you close, spellbound by his easy sorcery. You can feel the music in every word'' Martin Scorsese ''Robust, wry, gritty and wise'' Wall Street Journal ''Confident and well oiled. At times it has the mythic sweep of an early Terrence Malick movie'' New York Times ''Captivating... this is essential reading'' Rolling Stone ''Robertson is an immensely capable storyteller and a keen observer'' New Yorker
