The Led Zeppelin song Gallows Pole foreshadowed the masterful (but overplayed) Stairway to Heaven which appeared on their next album. The song introduces each stringed instrument one-by-one, with an increasing tempo. I love how the mandolin chimes in near the beginning, sounding almost like a piano. Gallows Pole also features a banjo, an unusual instrument in rock music. You can hear it kick in with the drums here.
More about that drumming: John Bonham is really playing more than just a steady beat. Listen for example here, exactly when Plant sings "upon your face a smile"--his drumming mimics the cadence of Plant's words.
Of course Gallows Pole wasn't standard rock fare to begin with. There's a whole long history behind the song and Led Zeppelin were late to the party. link
