The memorial was unveiled by Culture Minister Uroš Grilc, Mirna Peč Mayor Andrej Kastelic and Slak's widow Ivanka Slak. The ceremony was attended by numerous locals.

Designed by his nephew Tomaž Slak, the memorial consists of a stone pillar with a bronze portrait of the musician, 37 concrete slabs resembling accordion buttons, and a concrete bench.

Slak was born in 1932 in Jordankal near Mirna Peč, but he spent most of his youth at his grandmother in the nearby Mali Kal. He was encouraged to play the diatonic button accordion by his uncle before he entered primary school.

He started playing at parties with his Lojze Slak Trio, and formed a band in 1957 with a group of singers to develop his own genre of the traditional Slovenian folk music. He died in Ljubljana in 2011.
