Elton John- "Tumbleweed Connection"
Ten great classic songs. No throwaways. My favorites are "Where to now St. Peter?" and "Burn Down the Mission". I liked this album so much I sprang for the MFSL Ultradisc, many years ago.
Jethro Tull- "Thick as a Brick"
Just one long song, but definitely worth a listen if you aren't familiar with it.
