Actually, at the pre-concert of Distant Worlds II in Stockholm, David Westerlund held a lecture called: "From Blip-Blop to Art music" You can check out his website here: http://www.davidwesterlund.com/
Some info on the lecture: (can also be seen on his site)
As the title implies, this lecture investigates the historical development of videogame music, from using primitive sound chips to being performed by orchestras in concerthalls. The first half of the lecture focuses on the history and technological innovations, and the latter focuses on videogame music as a genre today. The lecture was originally ordered by the Royal College of Music in Stockholm, where it was first performed on Ocktober 27, 2009. It has since been performed in different venues, perhaps most notably the Stockholm Concerthall on June 12, 2010. The lecture is available in both Swedish and English (David has a teachers degree in English).
