It could have been a wonderful year for Soundgarden. The band had worked intensively in the studio and prepared the successor of the fine comeback album "King Animal". Instead, 2017 will be remembered as the blackest year in the history of the band from Seattle: the year in which singer Chris Cornell took his own life, hanged himself - unexpectedly, for the family as well as for the fellow musicians who had played a sold-out concert in Detroit with their frontman on the evening of the event. In the afternoon Cornell had tweeted cheerfully and sent a greeting to Motor City - "Finally back to Rock City!".
