The band spent most of the early months of 2011 in Australia, working on their debut album. Between January and April 2011
The Horrifying Truth was recorded with acclaimed Australian alternative rock producer/engineer Forrester Savell. The album was recorded between Sony Studios in
Sydney, and Forrester's studio at Sing Sing Studios in
Melbourne. It was co-produced by Matthews and Woolright. During this period, I Am Giant also supported
Slash and
Stone Temple Pilots during the Big Night Out concert in
Singapore.
The Horrifying Truth was released on 1 August 2011. Three days later, the band started a nationwide tour in New Zealand, called 'The Horrifying Truth Tour', which was followed by concerts with
Dead Letter Circus in Australia. At the beginning of 2012 guitarist Aja Timu left the band. Rather than replacing Timu immediately, the band brought in a variety of session guitarists for tours and recording including Andrew Kerr and Michael Triponel. I Am Giant started 2012 with another tour of New Zealand and Australia. They played at what was called the final New Zealand
Big Day Out, where they also shot part of the music video for "Purple Heart", with fans holding up frames from the video, which had been shot a week earlier. The video featuring event sponsor's
Speight's Summit Beer was debuted during the band's set later that day. That year the band toured Asia, including Manila, Bangkok, Singapore and Kuala Lumpur. They were supporting
Slash's tour in Australia, and a UK tour in support of the October 2012 UK release of
The Horrifying Truth. During this tour the band released a German version of the
I Am Giant EP, which included their cover of
Slipknot's song "
Duality" and a new track "Blood Money". I Am Giant also began working on tracks for their second album. In late December 2012 the band returned to New Zealand for a summer tour opening for New Zealand Rock Legends
Shihad. The band debuted the live version of "Blood Money", which was shortly after made available on
iTunes. ==
