I went to a Portland Arts & Cultural Alliance (PACA) event earlier this evening. Adam Ayan was on the panel.
The session was called "Creative Communications: The Business of Art"
It was about resources that were available to artists - all artists, not just musicians. Though, almost all of it applies across the board.
These are two website you should bookmark.
First, obviously is PACA - www.portlandarts.org
On PACA's website, look to the left for the "Resources" link. They have a big list of useful websites and organizations. Some I was familiar with, but there are a few that I saw which I will have to check out later. I'm not going to reproduce it here, but it's worth looking at. Direct link
The second is the Maine Arts Commission - www.mainearts.com
They have a ridiculous amount of information on their websites. They have event listings, a database of artists, mailing lists, programs and seminars, and even grant opportunities.
The discussion will be broadcast on the community channel. I'm not sure when. I'll find out and post it later. I think there will be a summary forthcoming on the PACA site too.
