A singer/songwriter whose vibrant melodies transformed him from an outsider into a chart-topping artist, Mika's kaleidoscopic music makes the most of the escapist, empowering potential of fantasies. On his 2007 U.K. number one hit single "Grace Kelly," the vibrancy of Mika's multi-octave, classically trained voice and clever, detailed lyrics reflected his traumatic early years, when music was his only source of hope. Mika's early albums, such as 2007's number one debut Life in Cartoon Motion and 2009's The Boy Who Knew Too Much (which reached a career-high number 19 in the U.S.), were larger-than-life examples of how his music spoke to other outcasts as well as a much wider audience. As time passed, his approach grew more down-to-earth, particularly on 2019's My Name Is Michael Holbrook and 2022's single "Yo Yo," but never entirely lost the magical reality at the heart of his music.

Born Michael Holbrook Penniman, Jr. in Beirut to an American-Lebanese mother and American father, Mika and his parents moved to Paris while he was still very young. It was there that he learned to play piano, and he wrote his first song at the age of seven. When Mika was nine, the family relocated to London; the frequent moves, incidents like his father being taken hostage at Kuwait's American Embassy, and bullying at school affected him to the point where he stopped talking. At age 12, he was homeschooled for six months. During this time, music became Mika's lifeline, and he soon began formal musical training, which included voice lessons with a professional Russian opera singer. When he returned to school, he became the head of the choir at St. Philip's School in Kensington and sang at the Royal Opera House.

While studying at the Royal College of Music in his teens and early twenties, Mika recorded with the Royal Opera House and created a jingle for Orbit chewing gum. He dropped out of school to concentrate on his music, taking inspiration from freewheeling songwriters like Prince and Harry Nilsson. His debut single, "Relax, Take It Easy," appeared in the latter half of 2006, along with the Dodgy Holiday EP. However, it was his next release, "Grace Kelly," that broke Mika in the U.K. Issued in January 2007, the song hit number one on the U.K. singles chart. His full-length debut, Life in Cartoon Motion, did just as well when it arrived on Casablanca Records a month later; it topped the U.K. album chart around the time it received a U.S. release that March. Mika went on to win the Brit Award for British Breakthrough Act and the Ivor Novello Award for Songwriter of the Year, and earned a 2008 Grammy nomination for Best Dance Record for "Live Today," among other accolades.

Ahead of his second album, Mika issued Songs for Sorrow, a limited-edition EP of songs that included illustrations by some of his favorite visual artists. For September 2009's The Boy Who Knew Too Much, Mika collaborated in Los Angeles with producer Greg Wells, Imogen Heap, and Owen Pallett. The album's vibrant exploration of adolescent angst built on Life in Cartoon Motion's success, reaching number one in France, number four in the U.K., and cracking the Top 20 in the States. Its lead single, "We Are Golden," was another Top Ten hit for Mika in the U.K. Following The Boy Who Knew Too Much's release, he was awarded the French Order of Arts and Letters in March 2010, and contributed the song "Kick Ass (We Are Young)" to the Kick-Ass soundtrack.

After spending much of 2010 and 2011 on the road, Mika opted for a more serious and straightforward direction for his third album. Inspired by the music of Daft Punk and Fleetwood Mac, as well as a near-fatal accident his beloved sister Paloma suffered, October 2012's The Origin of Love featured contributions from Wells, William Orbit, Benny Benassi, Pharrell Williams, and Empire of the Sun's Nick Littlemore. Around the time of the album's release, Mika officially came out as gay. In 2013, he became a judge on the seventh season of the reality TV talent competition The X Factor Italy, and issued the Italian compilation Songbook, Vol. 1 late that year. In 2014, he also joined the French TV singing competition The Voice: La Plus Belle Voix, where he remained as a judge for several seasons.

Following the 2014 French-language hit "Boum Boum Boum," Mika returned with his fourth album, June 2015's No Place in Heaven, another collaboration with Wells with a more mature sound informed by '60s pop music. The album became a Top Five hit in France, Italy, and Switzerland and reached number 19 in the U.K. That November, Mika released his first live album, L'Orchestre Symphonique de Montréal. Despite this success, his misgivings about the commercial side of music-making led him to take a break after the No Place in Heaven tour ended. In 2017 and 2018, he created and hosted the award-winning Italian variety show Stasera casa Mika while writing songs at his own pace. This relaxed creativity and openness seeped into 2019's My Name Is Michael Holbrook, which continued the more grounded style of No Place in Heaven but also left room for Mika's trademark flights of fancy. The album was a Top Ten hit in Italy and France, and reached number 57 on the U.K. Album charts. Mika supported My Name Is Michael Holbrook with a tour of Europe, North America, Australia and New Zealand, and in between live dates, appeared on reality competition shows including X Factor Italia and France's The Voice Kids. Early in 2020, the live album Live at Brooklyn Steel appeared.

Though the COVID-19 global pandemic forced him to cancel many of his 2020 tour dates, Mika remained busy. He appeared as a judge on X Factor Italia and performed at I Love Beirut, a streaming concert to aid Beirut following the August 2020 explosion in the city. Mika's participation in I Love Beirut led Lebanon to award him the Order of Merit. Late in 2020, he hosted the charity concert "Do Re Mika Sol" and collaborated with the Royal Opera of Versailles on a performance captured by the early 2021 album A l'opéra Royal De Versailles. For that year's Pride Month, he performed a live-streaming concert that benefitted Lady Gaga's Born This Way Foundation. Later in 2021, Mika returned to his judging duties on X Factor Italia and performed a pair of concerts at the Philharmonie de Paris that were broadcast on French and Italian TV. In May 2022, Mika co-hosted the Eurovision Song Contest with Laura Pausini and presenter Alessandro Cattelan; during the contest's finale, he performed his darkly pulsing synth pop single "Yo Yo." ~ Heather Phares & Marcy Donelson, Rovi
