That's a great point/question. There really isn't a hard and fast rule about that. I think my intention with the 'etc' category in the discography section was to list any Justin and Christian musical projects outside of Bishop Allen. I do like the idea of noting other musicians/contributors in the band - as a way of musical discovery - but I think it could get confusing quickly. You mentioned Michael Tapper. Including his solo album in the etc. does seem ok - but do we also list his contributions to other bands? For those connections - outside of the Justin and Christian - I think discogs has that covered as a source. So I think sticking with the way it is for now is ok. But by all means - let me know what you think.
