In July 2010 Rumble embarked on The Edge Winter Jam: The Experiment Tour, which had him perform in Auckland, Wellington and Christchurch.

The Experiment received mixed to positive reviews from music critics; some praised its catchiness while others labelled it "chart fodder".

Rumble's hip hop group, Fast Crew, released their second studio album, Truth, Lies & Red Tape, in 2008.

[1] The band split soon afterwards,[2] and Rumble decided to pursue a solo musical career, and taught himself to play the guitar.

[4] He explained that when he wrote songs for the album, he began by creating a chord progression using his guitar, which evolved into the tune's basic melody, after which he would determine its theme.

"Always Be Here" was the first song Rumble completed,[4] which he sent to record label Warner Music NZ, thereby commencing his solo career.

Sponsored by radio station The Edge, it also featured appearances by J.Williams, Kidz in Space and Ivy Lies; it was later announced that American rapper B.o.B would join the line-up.

[20] On 16 December 2009 "Don't Know What to Do" was released,[21] which reached number ten on the New Zealand Singles Chart,[22] and was also certified gold.

[29] Jacqueline Smith of The New Zealand Herald gave The Experiment four out of five stars, and praised its mainstream appeal and the variation within the album.

[9] Rip It Up's Matt Ruys awarded The Experiment four out of five stars, calling it "arguably one of the best New Zealand male pop records of the new millenium".

[33] Kristin Macfarlane from the Bay of Plenty Times was very favourable in her review of the album, and lauded its catchy tunes.

[8] Simon Sweetman of The Dominion Post gave The Experiment one star out of five and wrote, "This [album] will be shoved down people's faces as being great new music from New Zealand and it's not.

[35] The Experiment debuted atop the New Zealand Albums Chart on 5 April 2010, replacing Lady Gaga's The Fame Monster.
