as for still life...there was a band which also did one self titled album in the early 70s on the vertigo label. ironically the cover featured a bunch of pink orchids, and the font is strangely akin to an opeth logo. speculation still ensues however, due to van der graaf also having an album titled still life, as well as the term itself being fairly common and normal in the world of art and music, so whos to say really.
