Mellotronists

Ok, now I'm hooked on this.....I've been listening to Small Frozen 
North over and over for the last hour.  I simply must have more of 
this in my collection.  Is most of RMI's music similar to this?

My impression is that it sounds kind of like the parts of APP's "I 
Robot" mixed with liberal amounts JMJ's Oxygene part 2 (or is it 4?).

All I know is this is going on my CD's-to-be-bought list!
