Maybe we do need the voices of artists after all. Artists do have a history of seeing things before they become the norm in our society. Or, perhaps they are brave enough not to hide from distressing truths. Look at Joni Mitchell's Big Yellow Taxi from 1970. That song feels so peppy and fun in tone but its message was ahead of its time.
To say that rock legend Neil Young has been making waves on his ACFN 'Honour the Treaties' tour would be an understatement. His comments about the horrors of the tar sands have made front-page headlines, set social media ablaze, and have brought out more than a few attacks mostly from stalwarts of the oil industry.
