L.A.S., or Lachowicz Audio System, is the solo project of Jacek Lachowicz, known for cult bands Ścianka and Lenny Valentino. As L.A.S., he debuted with the album Szum in 2014; the music under this label is mainly singer-songwriter electronica, with occasional dance and experimental excursions. The show in Poznań marks the premiere of material from his latest album Zawieszony, consisting mainly of instrumental pieces for delicately prepared piano, with a strong ambient bent.
