They released their third album Led Zeppelin 3 a year later on 1970 , with more acoustic style that was strongly influenced by folk songs and Celtic music, showed band’s versatility. This album also moved to number one position in US and UK.

During their 12-year reign, Zeppelin released nine albums, sold an estimated 300 million units worldwide, shattered concert attendance records, and scored the third best-selling album in US history for Led Zeppelin IV (a.k.a. Zoso or Runes). Whatever alchemy went into creating them, there were a few key principles that Zeppelin adhered to from the get-go that played a role in their phenomenal success. Let’s take a look how they did it, and what you can learn from their example.

Led Zeppelin was different. Like table legs, the four band members bore the creative load equally. Each contributed to the group's songwriting. Plant, with his compelling voice and flowing locks, was the archetypal frontman, while the phrase "guitar god" seemed tailor-made for Jimmy Page. John Bonham was a larger-than-life character whose drumming was a distinct part of the Led Zeppelin sound. Just as vital to the success of the group was John Paul Jones' contribution on bass, keyboards and mandolin, not to mention his imaginative approach to songwriting and arrangement.
