Love Loud Music? Check Out the Trailer for the Doc on Marshall Amps

Back in the early 1960s, guitars seeking volume started making a beeline for Jim Marshall’s shop. Marshall, a drummer by training, had begun to make big, powerful, rugged amplifiers that were able to stand the rigours of this new thing called rock’n’roll.  There’s now a documentary on the history and impact of the company. Check out the trailer for Father of Loud. (More at Blabbermouth.)
