There are probably a few more, but other people have mentioned those on this forum at one time or another. http://www.myonlineband.com/ I don't see how to delete myself though on that one, and I have done nothing on it, and doubt if I will. Other websites will have to be searched on a search engine like google or startpage or another one that exists.

I don't know what they use for a DAW either, all kinds I suppose there at myonlineband.com.

As far as music, I like Sound cloud compared to all the others. I see they have a dropbox to share with from there now as well but I have never tried sharing anywhere so cant comment on that part.

Have you considered your own webpage.  Wix is free and easy to make one to your needs.

I hear that Google+ is particularly popular with artists wanting to share visual stuff.
