Jeez, I try to diversify from the norm and this happens.
Oh well, that is correct. I'll probably just give away the answers in a bit unless someone else comes in. If anyone else does come in, here are hints for them:
A1: 2011 album by Brazilian electronic artist.
A2: British folk singer-songwriter. Initials are FT.
A3: 1994 double album by British electronic duo. I pimped these guys in a thread once, and this is on /mu/'s list of essential electronic albums.
A4: This female artist was more prominent in the 90s, but still writes music. Has won and been nominated for many awards.
A5: Arguably the highest regarded trip-hop album of all time, other than Mezzanine by Massive Attack.
B2: Final album by the inventors of post-rock. They were synthpop earlier in their career and made a song that was made more famous by No Doubt.
B3: Kind of the pinnacle of "hipster" albums. Any conversation about this album seems to influence talk of hipsters.
B5: Debut of arguably the most important group in trip-hop.
C2: Sophomore album of this indie folk band released in 2011. Not Bon Iver.
C3: An incredibly famous and highly acclaimed artist. His initials are DB.
C5: Lo-fi indie band by elementary school teacher. Known for rarely writing songs over 3 minutes in length. The #1 ranked indie album of all time on Amazon.
D2: Known for having an actual dead man on the cover. This album is sometimes credited as a band of the same name as the album, and sometimes credited to a very prolific avant-garde composer. You can see an N.
D4: Debut of this dubstep artist. Not "WUBWUBWUB" dubstep, the more subtle kind. His sophomore album is much more well known.
E3: Highly-regarded album by an artist known for having an incredibly low, raspy voice.
E4: First album by the inventors of the Zeuhl genre. Yes that's a swastika there. If you don't know what Zeuhl is, try a google search and you'll end up finding the band and the album.
E5: I don't know what to say except Zander (Ravenheart) would likely kick your asses if you do not get this.
