That's fine because people who do visit the site will know what it is beforehand. It isn't for you. I'm more interested in criticism on its functionality (the actual app) rather than comments on the purposely limited landing page and judging a book by its cover like most people here seem to be doing.

I actually have a band and this app could be for me this summer. But I didn't get it at all the first time. The only reason I looked at it twice was that I found it here on HN. Not all your potential customers are the typical music-branch-guy. Also, something to easier distinguish different widgets would really help! User defined color or something.

I really like the one-man-army way. Keep it up, you got some good stuff going on!
