 Following the release of their second album , Led Zeppelin completed several more US tours . They played initially in clubs and ballrooms , and then in larger auditoriums as their popularity grew . Some early Led Zeppelin concerts lasted more than four hours , with expanded and improvised live versions of their repertoire . Many of these shows have been preserved as bootleg recordings . It was during this period of intensive concert touring that the band developed a reputation for off @-@ stage excess .
