Łukasz Krawczyk (born 1981 in Lublin, the biggest city in eastern Poland) is a rapper and member of the American hip-hop crew Verbal Vets located in Boston, Massachusetts. By the Americans he was nicknamed Luka, and the name stuck. He is the official promoter of the Natural Born Spitters in Poland. Formerly he was connected with Shyheim from New York City Wu-Tang Killa Beez as well as his Brock Brothers, Inc. A Management & Production Company. He did contribute to Polish-American affiliation and collaboration between TakZWani (TZW), and the Natural Born Spitters. Consequently, in 2005 they recorded a joint banger entitled "Nie Zabierzesz Mi Tego" (You won't take it away from me.) As a rapper, Luka is featured in the song entitled "Wykręcone Społeczeństwo" (Twisted people) by TakZWani from his home town.
He was a guest-on-the-air of the Radio Centrum (Poland) 98.2 MHz FM's broadcast called "Rapsesja" (Rap Session) in June 2004. A month later he was interviewed on (broadcasting by Polish Radio Lublin 89.9 MHz FM) "Champion Sound" which is an incredible achievement because few people are interviewed on air on this radio station. He knows (in person) one of the most popular Polish TV and radio hosts/journalists Hirek Wrona. There were some Natural Born Spitters' recordings in fall 2004 on the nationwide Trójka (Polish Radio Co. Program 3 in Warsaw) as a result of their cooperation. All the listeners of "Czarny Piątek" (Black Friday) were able to get to like the hip-hop directly from Boston. Furthermore, the whole Poland could hear about them.
