Well, that *is* a good question!Canna answer for the rest of the world, but for my little corner of the world...
We have embelished only a very few songs. We added a kind of reggae guitar track to a song that normally has only an acoustic guitar in it, but I do think it adds to the songs feel. We also completely re-recorded in studio at least one song from our most recent "live" album. I guess the lead singer thought it was not good enough for release.
Other than that, we're pretty much WYSIWYG (not to steal someone elses nom de plum).
