Merky ACE, also known as Splurt Diablo for his productions, is a grime MC from Lewisham, South East London. He was a founding member of grime collectives Family Tree and Tizzy Gang. His stage name is a play on his first name, Aisa.

Despite writing bars since the early noughties, he first rose to prominence in 2010-11, when he released several promo CDs and later Blue Battlefield, his debut mixtape. At the end of the year, he released the Catch Up EP. There was also talk of a forthcoming project entitled Treble Threat around this era which never surfaced.

The following year, he featured on Dizzee Rascal’s Dirtee TV 2 Mixtape. He also featured on Lord of the Mics III where he clashed Wolverhampton MC J1.

In 2013, he released two mixtapes: All or Nothing and Play Your Position, both under the record label NoHatsNoHoods. In the same year, under the alias Splurt Diablo, he produced the instrumental J3 EP, released by the Oil Gang label.

In 2014, he was signed to Dizzee Rascal’s record label Dirtee Stank. His first and only release with them was the Peak Levels EP (2015).

In 2015, Merky ACE pronounced Family Tree dead and formed a new grime collective, Tizzy Gang, alongside Tre Mission and Cadell. The collective also frequents members such as MIK and Vic Santoro.

In 2016, he released GOAT (a joint EP alongside MIK), Catch Up Vol. 2 and Vol. 3.

In 2017, he executive produced, vocalled and produced a significant portion of the Tizzy Gang collaborative album, Opps Next Door Volume 1.

His debut album, War is Normal, landed in May 2018. The project was preceded by the lead single “TDF”, and the previously-shared tracks “Ruff’s the New Buff”, “Black Hawk Down” and “What’s the Program?”.

To coincide with various Bandcamp fee-waiver days amidst the coronavirus pandemic, he released a number of new projects including Catch Up Vol. 4 and several Splurt Diablo beat tapes comprising some of his most sought-after instrumentals and VIPs. On 2 April 2021, ACE dropped the surprise album Sticks & Stones. It features 12 tracks, including “TDF 2” and the whole project has only two features (Slaughter and Lioness).
