Seth Sentry grew up in
Sorrento, Melbourne. Sentry's first public appearances were during live performances with Melbourne
hip hop and
drum and bass outfit, D.S.O.L. in 2003. In 2005 he reached third place in the Revolver Battles competition, in addition to organising and appearing in a weekly hip hop night at The Old Colonial venue in
Fitzroy—Sentry's involvement with the Old Colonial led to an appearance on
The Forthwrite Mixtape in 2007 and a guest appearance on
Pez's 2008 album,
A Mind of My Own. After posting a number of songs on Triple J's
Unearthed website, he was selected by Steph Hughes, host of the station's
Home & Hosed programme, as a "Featured Artist". Sentry's "The Waitress Song" became the most downloaded track on the website and went on to reach No. 31 in
Triple J's Hottest 100 of 2009 and appeared on the compilation
The Best of Australian Hip Hop Vol. 1. "Simple Game", Sentry's second single, received high rotation on Triple J. He followed with a 31-date national tour supporting Pez. In November 2008 Sentry independently released his debut EP,
The Waiter Minute, consisting of five songs including his previously released singles. Accompanying the upload to Facebook of the
conscious track "Strange Lot", he stated that he "wrote most of it in between train rides back and forth to work." In 2010, Sentry continued to tour and finalised the recording of his debut album with Melbourne producer Matik. In August 2010, he was a guest on
Horrorshow's "Our Song", ahead of a national tour with the group, and "Closer", a song by Australian hip hop artist
360. Sentry's debut album
This Was Tomorrow was released on 14 September 2012 on his label, High Score Records (distributed by Inertia Records). It was selected as the Triple J feature album in the week of its release. The album debuted at No. 6 on the
ARIA Albums Chart and remained in the top 50 for six weeks. Two of its singles, "Dear Science" and "Float Away", were listed in
Triple J's Hottest 100 of 2012 at No. 26 and No. 57, respectively. In April 2013, Sentry performed on the American late-night talk show
Jimmy Kimmel Live! singing "Dear Science" and "Float Away". He was the first Australian rapper to ever feature on a US talk show. In May 2013, Sentry completed the 'Dear Science' Australian tour, before announcing the larger 'Vacation' tour that featured support from Mantra and Grey Ghost. On 5 June 2015, Sentry released his second studio album,
Strange New Past, which peaked at No. 2 on the ARIA Albums Chart. In that same year Sentry broke the record for the largest Australian Regional Tour with 50 shows across the country. In May 2021, Sentry announced his third studio album,
Super Cool Tree House, which compiles songs released on
YouTube during the
COVID-19 pandemic. The album was released on 18 June 2021. == Personal life ==
