Illusion is the second recording of Eero Koivistoinen Quartet for Svart Records after the quartet's debut Hati Hati. The ensemble has worked together for five years, performing at festivals and clubs in Finland and the USA. Playing together for 5 years has made the ensemble tight and the interplay is happening. All members of the quartet are recording artists and playing busy in many other combinations as well.

Pianist Alexi Tuomarila released recently his second trio album Kingdom on Edition Records. Bass player Jori Huhtala just finished recording with his new trio Jori Huhtala 3.
