Joseph Ellis-Stevenson (born 19 October 1988) who now makes music under the name Dot Rotten. Zeph Ellis is a producer and MC from South London.

He started his career as ‘Young Dot’ (a reference to K Dot Kidman from Essentials Crew) and released a mixtape called “This Is The Beginning” and a Grime instrumental called Bazooka to become a heavyweight in the scene.

While named Young Dot, Ellis changed his name yet another time to ‘Dot Rotten’ confirming this with “R.I.P Young Dot” a classic mixtape.

Having worked with a lot of people in the scene his beats and instrumentals have been used by a barrage of MC’s. A generous sport in terms of beats, Ellis released a ton of instrumentals known as Rotten Riddims Volume 1-7. Rotten Riddims Volume were for free.

In 2023, Dot adopted a new persona using the name “Rottimeus.D.Gruffy” (for his MC'ing) and “Rottimeus Grxme” (for his production).
