The Beatles - Abbey Road, Sgt Pepper, Let it Be, Revolver, Rubber Soul, AND the White Album. All completely amazing all the way through.

The Grateful Dead - American Beauty

Big Brother and the Holding Company - Self titled

Daft Punk - Discovery

I could go on and on... I feel a lot of older artists put more work into their albums, and there was less of a drive to mass produce garbage (though it definitely still existed. Eat my butt, Monkees). Also, back before cassette tapes, CDs, and mp3s, one had to actually get up and hustle over to the record player to lift the needle and change the song... too much work, so they gave us great music xD
