Tidal, Jay Z’s streaming music company that promises something different while copying Spotify’s layout, is without a CEO. In a letter to investors, Tidal mentioned now-former CEO Andy Chen had left, replaced by his predecessor Peter Tonstad. Citing Tonstad’s “clear vision” for what Tidal is trying to sell do, the company also says he’s “streamlining resources”. That dovetails with another report that up to 25 employees are now gone from Tidal, including Chen. Apparently, Jay Z is also calling everyone to let them know.
