Eero Koivistoinen Quartet: Eero Koivistoinen (tenor and soprano sax), Alexi Tuomarila (piano), Jori Huhtala (bass), Jussi Lehtonen (drums). 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. Drummer Jussi Lehtonen is making his Svart Records debut at the same time with his Quintet recording Move On. 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. This recording session was the last one made in the famous M1 Studio of YLE (Finnish Broadcasting Company). The title Goodbye M1 is dedicated to the studio where I myself and so many others have had a number sessions and memorable moments during the 35 years that this sidewise largest studio in Finland was still active.
