Kirill Aleksandrovich Tolmatsky (; 22 July 1983 – 3 February 2019), better known by his stage name Detsl (Russian: Децл), was a Russian hip hop artist. In 2000, he released his debut album Who? You to massive success and quickly became a teen idol of the early 2000s in Russia. In 2001, his second album Street Fighter was released.
He died on 3 February 2019 in Izhevsk at the age of 35 from a sudden heart attack after performing his live set at the private birthday party. In a 2007 interview, Detsl talked about faking his own death at the exact same age while performing at a concert in the same city he would actually die in.
