Northern California plays host to another Bandwidth Conference starting this afternoon, and plenty of familiar names are flocking to the event.  The San Francisco-based confab generally attracts a modest-yet-savvy crowd of technology and music executives, often from the Bay Area.

But digital music is a global industry, and that means plenty are also hopping on a plane to play.  The includes Charles Caldas, CEO of Merlin; Jeff Price, CEO of TuneCore; Ian Rogers, CEO of Topspin; Livia Tortella, GM/EVP of Marketing and Creative Media at Atlantic Records; and Josh Rosenfeld, Cofounder and President of Barsuk Records.  Ex-EMI executive Cory Ondrejka is now off the bill.

The real action starts Friday, though some ‘library sessions’ will warm things up later today – an appropriate characterization given the University Club venue in Nob Hill.  Open forum discussions will canvass topics like startup stress and marketing data (or lack thereof), and a healthy batch of interviews and case studies are also part of the fun.
