His debut album "Bumerang" was one of the most-bought albums in 2015 and 2016. Its circulation exceeded 90 thousand. copies.
 "My House" is a pictorial story of a breakdown of a relationship, set in four walls and 9 acts. The record was made by people from Kortez's closest circle. It took 18 months to work on it. The producer, just like the case of "Bumerang", was Olek Świerkot. Kortez recorded most of the instrumental parts with his band mates (Krzysztof Domański, Kuba Galiński, Lesław Matecki and Marcin Ułanowski). Agata Trafalska, who worked on them with Kortez, was responsible for the texts. They were helped by: Roman Szczepanek (known from "Bumerang"), Mateusz Dopieralski (Bitamina) and Maks Kucharski (former roommate of Kortez from the Max Fiszer duo).
 The whole picture of the album is complemented by a cover, inspired by the front of the album "Blues" by Brekout. The cover photo was taken by Konrad Prajsnar, Kortez's closest friend. The album is announced by the single "Dobry Moment", which the day after its premiere became one of the most popular films on Polish YT.
