question:
Question: How many features did Brecht and Dudow work on together? Passage:Dudow was born in Zaribrod, Bulgaria (today Dimitrovgrad, Serbia). In 1922, he emigrated to Berlin with the intention of becoming an architect. He gave up this plan and began studying theatre in 1923, first under Emmanuel Reicher, and then, from 1925 to 1926, as a theatre studies student under Max Herrmann at the university. He worked with Leopold Jessner and Jurgen Fehling, served as a chorus member under Erwin Piscator, and was a director's assistant to Fritz Lang on the production of Metropolis. During this time, Dudow also ran a bookstore with his wife and worked as a foreign correspondent for a Bulgarian newspaper. In 1929, he visited the Soviet Union, where he met Vladimir Mayakovsky and Sergei Eisenstein in Moscow and eventually, Bertolt Brecht. After his return from the USSR, Dudow directed Brecht's theatrical piece, The Decision (Die Massnahme), and began his film directing career. He was commissioned by the left-wing, Soviet-German production company Prometheus-Film to direct a short film, Wie der Berliner Arbeiter wohnt (1929), as part of the documentary series Wie lebt der Berliner Arbeiter? Dudow's first feature, Kuhle Wampe (To Whom Does the World Belong?, 1932) was a collaboration with Brecht (who provided the script and helped finance the project), Hanns Eisler, and Ernst Ottwalt. It was banned because it was perceived as being politically subversive.

question:
Question: On what label does Hammer's debut album appear? Passage:Before Hammer's successful career (with his mainstream/commercial popularity lasting approximately between the mid-1980s until the late-1990s) and his "rags-to-riches-to-rags-and-back saga", Burrell formed the Christian rap music group Holy Ghost Boys. Some songs produced were called "Word" and "B-Boy Chill". "The Wall", featuring Burrell (it was originally within the lyrics of this song he first identified himself as "K.B." and then eventually M.C. Hammer once it was produced), was later released by Jon Gibson (aka "J.G."). This was Contemporary Christian music's first rap hit ever (by anyone), in particular by a Caucasian (Gibson) and/or from a duo. The track appeared on Gibson's album Change of Heart (1988), and "Son of the King" showed up on Hammer's debut album Feel My Power (1987) as well as the re-released version Let's Get It Started (1988). Burrell, along with Tramaine Hawkins, performed with Gibson's band doing several concerts in various venues such as the Beverly Theatre in Beverly Hills.
