With the launch of his latest album ‘A Letter Home’ out of the way, musician Neil Young is stepping up his involvement in PonoMusic, his partially Kickstarter-funded high-definition music startup. On Friday, the company announced that its current CEO John Hamm is stepping down, although he remains an investor. Young will replace him as CEO, while his attorney Rick Cohen is stepping into a role as chief operating officer. “PonoMusic has been a mission of mine for many, many years, and I’m more passionate than ever about the prospects for its success,” said Young in a statement published on PonoMusic’s Kickstarter updates page, which also suggested that the company’s music device and downloads store are on track for a full launch later this year. PonoMusic has also appointed veteran music producer Bruce Botnick as its head of content acquisition, tasked with striking deals with labels to add their music to the company’s store.
