Bronfman told a technology conference that the combination of EMI’s recorded music division with Universal’s as well as its publishing unit with Sony/ATV’s would create overly dominant global players that could harm new digital music platforms and crimp payments to artists.

Vivendi’s Universal and Sony Music’s Sony/ATV announced in November that they would split EMI in two and purchase the parts for $4.1 billion combined.

Bronfman says Warner would actively fight to stop the deal.
