I'm too lazy to read everything but I'm willing to help with anything that I'm capable of, I own two labels in real life and I collaborated with booking agencies and have some knowledge about events in the music area(usually eletronic) - we can make a proper business if it's done right here. Would be nice to have a way to stream mixes through radios inside clubs, I'd love to see more diversity, rather than boring commercial music in clubs. I'm thinking a podcast series weekly where people can actually show their real life work in terms of music (from ambient to rock, whatever is their passion), along with interviews, photographies, etc.
I remember owning a pseudo-fashion design house with some friends but we didn't had the time to take care of it - I'd love to see something like that too.
Everything else sounds great, from museums to journalism. We could make some Andy Warhol type of business here and combine them all into one unique hub of arts, one huge group of friends that combine music with photography, film, painting, journalism, and so on - this is just my main idea, but I'd adore to see this made properly with a touch of the 70/80s, people being all artsy-partsy and developing characters in that way.
