"Ecstasy" was released as the second single from ATB's album No Silence.
It is characterized by its upbeat tone, crisp layering, and memorable intro. Vocals were provided by Tiff Lacey, who is also featured in the song "Marrakech." Ecstasy, one of ATB's more recent hits, is now among his most well known songs. It samples Jocelyn Enriquez's song "A Little Bit of Ecstasy".
