I have narrowed it down as follows, but you may wish to add your own or argue these:
Solid Pleasure, Claro Que Si, You Gotta Say Yes - The Carlos Peron and experimental period/era 1
Stella, One Second - The beginning of the collaboration era (Rush Winters, Billy Mckenzie, Shirley Bassey) also the breakthrough and movie era which could continue into Flag as the race was used in many movies since e.g. Nuns On the Run
Flag, Baby, Zebra - For me the Golden Era (as I think these are my fave 3 albums apart from Touch Yello), but also the Brass Era as this was where Boris got big with his Trumpets, Saxes and Trombones!
Motion Picture, Pocket Universe, The Eye - Back to experimentation and Collaboration era 2. I feel they needed to do Motion Picture and The Eye in order to achieve Touch Yello in terms of sound and flow. It's funny that a leaflet that came with my Touch Yello (basic addition) that shows their previous work doesn't show Motion Picture and how it's not a fan fave on this form either! Boris was experimenting with other vocalists beyond Dieter on The Eye too, a thing he of course continued with Heidi and himself on Touch Yello.
Touch Yello - To the Future through the Past! - The next era. A new more defined Yello sound and audio-visual.
What are people's thoughts? - Would you move any of these albums into other lists/eras?
