The first 5 albums are really classy, granted proggy, but very good, 'Tales From Topographic Oceans' takes some getting into but I used to listen to it in my bedroom on cassette a lot in 73/74 and became quite familiar with it, I think there music takes quite a few listens. 'Fragile' is my favourite.
I think that some of their material can be difficult due to its symphonic/rock cross overs which can be confusing IMO.
