I didn't mean using splash pages with SEO'd content for the band as much as wondering why they aren't considered cloaking if they are practically re-directs as well no?
Some are, yes, but some aren't. Many splash screens just require you to "Click here", or if they automatically redirect, generally they're just an image and contain little-to-no other content (kind of the way yours is, with the video clip at the beginning) - that's generally why they're not such a great idea, because you want your site's main index page to display some content relating to what your site's about, perhaps a small index of recently added pages with snippets from each page, navigation, etc. with all the other pages on your site linking to it, giving search engines the impression that it's the most important page on your site (which, generally, it is).
The use of scrolling DIVs on some of your pages will definitely help, they're a great alternative to the use of frames/iframes. But, this isn't going to get around wanting to have the music playing continuously as the user browses through your site - unless you could tap into IE's "Media" bar, although this won't help you with FF or other Non-IE, Non-Windows combos of visitor.
You're in a tough spot if the band doesn't want visitors browsing a HTML version, but then, you're going to have people on limited technology PCs that can't display flash (or don't want to install the flash plugin), as well as people on dialup that don't want to have to download all the media, etc.
I'd just explain to the band the benefits of having an HTML site running parallel with their flash version; SEO, low-bandwidth visitors, general compatibility and - as you mentioned regarding your own site - accesibility.
Probably about 80-95% of the traffic on my websites comes from Google, or other search engines. Without that, my sites would've been nothing. Yes, now there are many other sites out there linking to mine, but if not for the search engines telling them I exist in the first place, most of those links would've never appeared.
P.S.
You seem to know your stuff, what is your speciality? we always seek out creative freelancers to work with (development, design, etc`) preferably London, UK.
I'll send you a PM
