The debut, cut in a matter of days: heavy blues rock that set the template for everything the band did next. It includes "Dazed and Confused" and "Communication Breakdown".

Recorded in snatches while touring, heavier and denser than the debut. It opens with "Whole Lotta Love" and its famous riff.

A turn toward acoustic and folk material, much of it written at the Welsh cottage Bron-Yr-Aur. The driving "Immigrant Song" opens the record.

The officially untitled album marked by four symbols on the sleeve, the band's best seller. It carries "Stairway to Heaven".

The band widens its palette with funk, reggae and orchestral keyboards. It holds "The Song Remains the Same" and "No Quarter".

A double album spanning everything from heavy riffs to acoustic pieces. Its centrepiece is "Kashmir".

Recorded fast while Plant was recovering from a car crash, built almost entirely on guitar with no keyboards. It opens with the ten-minute "Achilles Last Stand".

The last studio album made in Bonham's lifetime, with Jones's keyboards well to the fore. Among its songs are "All My Love" and "Fool in the Rain".
