SECRET RULE was founded in 2014 by lead vocalist Angela Di Vincenzo & guitarist/producer Andy Menario. The following year SECRET RULE released their debut album "Transposed Emotions". The music of SECRET RULE is a blend of heavy guitar riffs, electronic elements, symphonic keyboard parts, and very powerful yet catchy vocal lines. Their sound is unique and intriguing.
Their energetic performances captivate the audience's attention, leaving them spellbound each time.

During September 2017, SECRET RULE released a music video for "The Song of the Universe", their hit single from the third album, "The Key to the World". The video was well received both by critics and fans, with over 2 million views on YouTube.

In February 2018, SECRET RULE opened for Serenity and Visions of Atlantis on the "Symphonic Metal Nights tour". It was a huge success that brought SECRET RULE to a higher level.
For the month of May 2019, The 7 Endless debuted at 20° in the Japanese chart among the best imported albums for the magazine "BURRN!".

In February 2020, they will release their fifth album, but due to the pandemic, all live activities will be halted.
In April 2020, forced to stay at home, they released "Quarantine: the other side of us", a collection of cover songs from various genres arranged with their unmistakable sound.

Almost two years after stopping tour activity due to the pandemic, Secret Rule returned to tour in May 2022 as direct support for Visions of Atlantis and in July for Semblant.
Their songs reached the top 10 on iTunes rock/metal/all genres charts in countries such as Finland, Japan, Italy, Canada and Norway.
