Hoste was born in Ghent, Belgium. Being the youngest from a family with 4 siblings, he grew up in an environment of entrepreneurs. His father worked in the distillery business while his mother worked as a personal assistant for a German company. Already from a young age, Hoste created a passion for singing. However, at the age of 11, his doctor told him that he would lose his voice by the age of 30 if he would continue, which made him give up singing. At the age of 26, Hoste left Belgium to start a career in the aviation. After taking up roles with Thai Airways International, former Belgian national airline Sabena and Virgin Atlantic, he eventually moved into logistics, trading and consultancy shifting between Europe and Angola. In 2018, Hoste met Australian playwright and former Neighbours actor Alex Broun. With the help of Broun, he created the Best of Broadway show, which he performed in the Madinat Theatre in Dubai. In 2020, Hoste and Broun worked together on Don't You Forget About Me, a cinema-meets-concert production which the two described in The National as "an interactive live cinema experience”. In the show, cruise ship-singer Oliver (Hoste) falls in love with cover girl Chloe (played on screen by actress Suzie Demetri Robertson). Hoste performed this show in several theaters in Dubai including VOX Cinemas. In 2021, the show was renamed to Love Beyond The Sea and was performed by Hoste on Queen Elizabeth. In November 2020, Hoste collaborated with Indian musician Nikhil Uzgare, the first independent artist to be signed on to Universal Music MENA, on A Night of Classical and Acoustic Rock, which they performed in Dubai Community Theatre and Arts Centre in Mall of the Emirates. The show, including songs from bands such as A-ha, Simple Minds, The Police and singers such as Frank Sinatra, Louis Armstrong and Andrea Bocelli, also featured Belgian pianist Clarissa Zaruk, Belgian vocalist Annekatrien Van Wassenhove and Russian musician Ivan Kovalenko. In May 2021, Hoste, Spanish soprano Isabel Cañada Luna and Kovalenko joined forces for Immortal Songs - Best of Crooners, Musical and Opera. In August 2021, the show was renamed to The Movies Night Live and the musical partners focused on interpreting soundtracks from blockbusters such as Moulin Rouge!, Ghost: The Musical and The Godfather.
