The concert performance "Kāda laimīga sagadīšanās" takes place on 19 September 2026 at Mazmežotnes muiža in Mežotne. The vocal-instrumental group "Aģenti" from Liepāja Theatre unites actors of different generations, including Edgars Pujāts and Armands Kaušelis, known for their improvisation and stage presence. Created as a tribute to Liepāja's 400th anniversary, the concert programme features a diverse mix—songs from theatre productions, dedication pieces, acoustic sing-alongs, and Latvian classics by composers Jānis Lūsēns, Imants Kalniņš, Jānis Strazds, and Uldis Marhilēvičs. Guests can expect an engaging evening blending music and theatre in a unique atmosphere. The event is held at a single venue.
