Zep leaned heavily on the blues for the two albums recorded in 1969. But they had already planted the seeds for their own thing by then.

There's an excellent essay by Robert Palmer where he dissects the music of Zeppelin, and how it compared to the blues as their songwriting evolved.

Exactly what point are you trying to make anyway?
