1) The Velvet Underground "Loaded"
4) The Pixies "Trompe le Monde"
5) Tom Waits "Rain Dogs"
Sorry. I know the point is not to respond to your lists, but still, I am shocked (shocked!) that these are not The Velvet Underground, Doolittle, and Closing Time, respectively. I can understand the choice of Rain Dogs (it's my second-fave), but the first two just perplex me, sorry.
that (totally unnecessarily) said,
Some Essentials. They are not in an order mostly.0. Miles Davis, Kind of Blue (ZERO because I think that, tied with the first two Velvet Underground albums, it is essential not in an essential albums way, but more in the way that oxygen is, in that I hesitate to even have it im my list)
1. Neutral Milk Hotel, Aeroplane over the Sea
2. Sonic Youth, Washing Machine and/or Murray St.
3. They Might Be Giants, eponymous and/or Flood
4. Ry Cooder, Into the Purple Valley
5. Some Bob Dylan album. I'd say Blood on the Tracks or Bringing it All Back Home
6. Nick Drake, Pink Moon
7. Patti Smith, Land
I'm sure I'll think of more. I am the list-writing kind of geek.
Edit.
Here I am again.
It's been a long time since I was significantly into punk, but I disagree fervently with your choices for necessary punk albums, so I've formulated my own.
1. Television, Marquee Moon
2. X-Ray Spex, Germfree Adolescents
3. Richard Hell & the Voidoids, Blank Generation
4. Zounds, The Curse of Zounds
5. Stiff Little Fingers, Inflammable Material.
I'm going to not say anything about the Sex Pistols.
And I will try to go a week without making any subsequent lists, as I think I have a problem.
