This week's traditional Wednesday Question saw the people of UG community debating the matter of the greatest collaboration album of all time.
We received plenty of votes and over 350 comments, all of which were summed up into a Top 25 rundown.
Note that we were looking for collaboration efforts between two or more artists, and NOT supergroups.
Before kicking things off, honorable mentions include Sunn O))) & Ulver with "Terrestrials" (2014), Scott Walker + Sunn O))) and "Soused" (2014), Fripp & Eno with "Evening Star" (1975), Tony Iommi & Glenn Hughes with "Fused" (2005), and Jello Biafra & Mojo Nixon with The Toadliquors and "Prairie Home Invasion" (1994).
With that out of the way, the list patiently awaits below.

You folks were apparently in some bossa nova mood this week! Marking the second appearance of Mr. Stan Getz, up next is the man's 1962 collaboration with Charlie Byrd called "Jazz Samba."
16. Robert Rich & B. Lustmord - Stalker (1995)
When two of the biggest dark ambient artists join forces, you get one of the darkest albums of all time. Inspired by Andrei Tarkovsky's 1979 film "Stalker," 1995's "Stalker" by Robert Rich and B. Lustmord is up next.
15. John Frusciante & Josh Klinghoffer - A Sphere in the Heart of Silence (2004)

6. The Velvet Underground & Nico - The Velvet Underground & Nico (1966)
A complete flop upon its release, "The Velvet Underground & Nico" grew into one of the most influential albums of all time. It's not for everyone, but the impact cannot be denied.
