He added the album had been years in the making.
Some of the tracks he had started composing years earlier.

Rudd cited influences for the album from Beatles drummer Ringo Starr and Free/Bad Company's Simon Kirke to Mountain's Leslie West and bandmates Malcolm and Angus Young.
Earlier Rudd told the Bay of Plenty Times an AC/DC tour with the band's new album was imminent and it "is not a case of if but when", although no dates had been confirmed.
The band has just recorded the album in Canada.
Head Job was released on Friday to Australia and New Zealand under record label Universal and will be then released digitally worldwide.
