Alright, I'm thinking suites of songs that are shorter than an album side. Some that I particularly enjoy are:
Robert Palmer, Sneakin Sally through the Alley, beginning of side 1 -- "Sailing Shoes"/"Hey Julia"/"Sneakin' Sally through the Alley"
Rupert Hine, The Wildest Wish to Fly (US version), end of side 1 -- "I Hang on to My Vertigo"/"Firefly in the Night"/"A Golden Age"
Planet P Project, Pink World, end of side 3 -- "Behind the Barrier (Pt. 2)"/"March of the Artemites"/"This Perfect Place (Pt. 2)" -- all of side three is dang near perfect, but it comes to such a wonderful crescendo with the March of the Artemites suite.
This all came about because I saw a song that I couldn't think of hearing without hearing the song that immediately follows it. If I had to encode this in MP3 format, I'd wrap it up all as one file.
Do you have any that you'd like to mention? Single song suggestions and side-long submissions will be immediately disqualified, pointed to and laughed at.
