Found this thread on progarchives and I thought it was interesting. Rules are:
1- It has to be prog.
2- You can't use the same band twice.
Here's my list:
2000: Estradasphere - It's Understood
2001: Maudlin Of The Well - Bath
2002: Pain Of Salvation - Remedy Lane
2003: Kayo Dot - Choirs Of The Eye
2004: Ayreon - The Human Equation
2005: Opeth - Ghost Reveries
2006: Uzva - Uoma
2007: Sleepytime Gorilla Museum - In Glorious Times
2008: Beardfish - Sleeping In Traffic Part Two
2009: Present - Barbaro (Ma Non Troppo)
Bonus:
2010: Haken - Aquarius
2011: Leprous - Bilateral
2012: Anathema - Weather Systems
2013: Gorguts - Colored Sands
2014: PoiL - Brossaklitt
2015: Guapo - Obscure Knowledge or Anekdoten - Until All The Ghosts Are Gone
2016: Free Salamander Exhibit - Undestroyed or Voivod - Post Society
2017: Major Parkinson - Blackbox or Ne Obliviscaris - Urn
It was hard.
