25 years from now, when this planet is a desert wasteland teeming with radioactive toxins and humans flying around on jet packs, the Rock And Roll Hall Of Fame will house a collection of MacBooks and iPods alongside other music-related iconography like Janis Joplin’s psychedelic Porsche and Michael Jackson’s threads. From dance clubs in London and concert halls in New York to warehouses in Los Angeles and across world, the pale glow of a bitten apple gleams from the laptops of DJs who owe their careers to these pieces of technology and, by extension, to former Apple C.E.O. Steve Jobs. In light of Jobs’ death yesterday, CMJ has compiled a collection of Tweets from some artists who took to Twitter to pay their respects, say their thanks and bid Mr. Jobs a fond farewell.
