Slot's compelling sound is built around duelling male and female vocals and infused with elements of hip-hop, metal and grunge. Shared vocal duties allow for a lyrical and harmonic dynamism rarely found in metal. Igor Lobanov's delivery tends towards aggressive rap, while the female vocalists who have fronted the band have each brought their own individual strengths. Uliana Elina's vocal dexterity allows her to switch from piercing cries to powerhouse melodicism in a heartbeat, while Daria Stavrovich's incredible vocal range harks back to some of rock's greatest female vocalists.
