The Ghost of RubangB on 10 April 2009
I think the most influential album of all time is Sgt. Pepper's, but then again, that was just a ripoff of Freak Out! by the Mothers, so I'm actually going to go with Freak Out! by the Mothers.
Thriller was a selection of incredible songs, but all it did as an album was put a bunch of incredible songs in a row. Freak Out! invented the concept album and changed the way people made albums. Now albums get intros and outros and have songs that share similar themes, or even song cycles or rock operas.
