Some good stuff there. Also from La Pandera. Now you've stolen my thunder, here's part 3 of my list
11. Pink Floyd - Meddle. My favourite Floyd period (I also love Saucerful ... and Atom Heart Mother). They were still psychedelic, but were also going beyond the confines of writing a collection of songs. Echoes is their classic long piece, starting out with a mysterious evocation of a void (a submarine?) which softens into almost pastoral harmonies, developing into a dark instrumental section, before returning to the calm of the vocal harmonies.

12. King Crimson - In the Court of the Crimson King. It was a toss up between this and Red, but I've already posted half of Red. Robert Fripp's combo has had almost as many changes as The Fall, but has always included the cream of jazz-rock musicians. The album starts out with the jazz-rock force of nature 21st Century Schizoid Man, before moving into a couple of more whimsical numbers (Talk to the Wind, Epitath, Moonchild which does include the prog excess of a silly drum section), before ending with the "Stadium Prog" of (almost) the title track. Technically brilliant, mostly either beautiful or terrifying, on occasion over the top.

13. Led Zeppelin IV - A classic rock band, influenced by many forms of music, but in particular by folk and blues. Sandy Denny sings on the Battle of Evermore. When the Levee Breaks is a reworking of a 20s blues song. John Bonham's drumming together with the harmonica create a real tension. Also, there's the song that you're not allowed to play in guitar shops.

14. The Beatles (The White Album) There are songs on this album which I wouldn't listen to on their own (e.g. Ob-La-Di, Ob-La-Da), but the White Album just creates a whole. In addition, there are some classic songs e.g. While my Guitar Gently Weeps, Happiness is a Warm Gun, Blackbird.
