King Of The Opera, formerly known as Samuel Katarro, is the musical project of Alberto Mariotti, songwriter from Tuscany, Italy.

King Of The Opera was first introduced to the public at the renowned Primavera Sound festival in Barcelona in the Spring of 2012. The project's strength lies exactly in this continuous search of the meeting points between seemingly irreconcilable genres: distorted punk-blues, bewildered (and bewildering) folk ballads and digressions into the acid realm of psychedelia.

After receiving praise from important musicians like Julian Cope, Patti Smith and David Thomas from Pere Ubu, King Of The Opera completed two European Tours throughout SwitzerlandGermany and France. The lead single "The Floating Song" from the album “Nothing Outstanding” was presented on the prestigious stage of the Ariston Theatre in Sanremo at the 2012 edition of Premio Tenco.

A lot of recognition also come from the world of cinema with the participation in various events of international significance such as Venice Film Festival, Milano Film Festival and Courmayer Noir Film Festival, also the song "Pink Clouds Over the Semipapero" is included in the soundtrack of the movie "La donna giusta" directed by Brando De Sica. In 2013 Mariotti had the chance to meet Patti Smith and play as opening act to her concert in Prato, Italy.

In 2016 King Of The Opera released his new album Pangos Sessions, ten songs that summarize his musical career in a pretty original way, alternating acoustic reinterpretations from King of the Opera / Samuel Katarro songbook and five cover songs (originally released in Mariotti’s birth year), by The Cure, The Waterboys, The Replacements, Tom Waits and Sonic Youth. The collection also includes the unreleased alt-folk-ballad “By the Shore”.

In 2017 he performed an acoustic solo set at the Hoxton Hall Theatre in London and in the same year he collaborated with the legendary Italian new wave band Diaframma for the song "Giorni".

The new album "Nowhere Blues" was released in January, 2020.
