A couple weeks ago, Foundry Group portfolio company Topspin Media’s CEO Ian Rogers delivered the keynote speech at the Grammy Northwest Music Tech Summit. He just posted his presentation on Topspin’s blog — if you have any interest in the current (and future) state of the music business, it is well worth a read. As I’ve mentioned before, I’m honored to be a part of Topspin, and think Ian is one of the most cogent thinkers out there about the intersection of technology and the music business. His post made it on to Boing Boing today, so I’m sure his keynote is getting a ton of well-deserved attention. Good stuff.
