“Keep It Simple” is the credo that Placebo bass player, Stefan Olsdal, proclaims in the latest video short from the Hamburg leg of the A ROCK tour. Not exactly the kind of angsty musing you'd expect to roll off the tongue of a seasoned rock legend, but over their 18 year history as a band, simplicity has been a key element. Olsdal discusses the Placebo effect at last month's beer and sweat soaked concert in Hamburg, the penultimate show of their whistle-stop European tour which heralded the launch of the slick new Mercedes-Benz A-Class.
