The follow-up to Supernatural came three years later and was highly anticipated by international media and fans alike. On October 22, 2002, Shaman was released worldwide. Although it initially sold briskly (298,973 copies in the US in its first week) and debuted at number 1 on the Billboard 200, the album's appeal quickly wore off and it soon slid down the charts. Despite this, it went on to sell 2x platinum in the US, and achieved platinum status in several other countries including Australia. The first single released from the album, "The Game of Love", which featured vocals from Michelle Branch, debuted at number 5 on the Hot 100. The album's next four singles failed to chart in most countries, but the final single, "Why Don't You & I", featuring the vocals of Alex Band, reached number 8 on the Hot 100. Musically, the album was a return to a more conventional sound for the group, with a mainly Latin rock-based sound.  With their renewed appeal worn off, another three-year wait saw the release of 2005's All That I Am. The album debuted at number 2 on the Billboard 200 but fared worse internationally, and quickly lost appeal. The album, a continuation of the Latin-rock influenced sound of Shaman, achieved gold certification in the US. A five-year break from recording saw the release of another studio album, 2010's Guitar Heaven. Musically it was a drastic change for the band, with a far heavier sound at its core and strong heavy metal influences. It debuted at number 5 on the Billboard 200 but marked another decline for the band, failing to achieve gold status.  In 2012 the group released Shape Shifter, which returned to the conventional Latin rock sound and was completely album-oriented, as no singles were released from it. It debuted at number 16 on the Billboard 200.
