Sam the Kid (Samuel Martins Torres Santiago Mira), born in July 17th, 1979, is the most known, successful and prominent Portuguese rapper/producer.

STK's debut album, Entre(tanto) (1999) was considered by all a mark to Portuguese hiphop culture.

In 2001 Sobre(tudo) comes out. An album in which Sam the Kid shows a major improvement and musical maturation.

In that same year (2001), he released an instrumental album entitled Beats Vol 1: Amor. Using resources like vinyl, discs, soap-operas, videos and recorded phone calls among others, STK created a superb and unique audiophilic world, inspired by the love of his parents, to whom he dedicated the album.

In 2005 he participated as an actor and music producer of O Crime do Padre Amaro. He actually has his own IMDb profile.

December 8th, 2006: The new album Pratica(mente) comes out. Highly expected and anticipated, this new album features lots of Portuguese artists such as: Melo D, Cool Hipnoise, Lil John from Buraka Som Sistema, Kalaf, Valete, Cruzfader, NBC, G.Q. and Carlos Bica.
Pratica(mente) is the first STK's album recorded in a studio, all of his past works were recorded at home.
