Chopin made his last public appearance on a concert platform at London's Guildhall on 16 November 1848, when, in a final patriotic gesture, he played for the benefit of Polish refugees. By this time he was very seriously ill, weighing under 99 pounds (i.e. less than 45 kg), and his doctors were aware that his sickness was at a terminal stage.
Where was Chopin's last public performance?

Control of labour and inter-group conflict is characteristic of corporate-level or 'tribal' groups, headed by a charismatic individual; whether a 'big man' or a proto-chief, functioning as a lineage-group head. Whether a non-hierarchical system of organization existed is debatable, and there is no evidence that explicitly suggests that Neolithic societies functioned under any dominating class or individual, as was the case in the chiefdoms of the European Early Bronze Age. Theories to explain the apparent implied egalitarianism of Neolithic (and Paleolithic) societies have arisen, notably the Marxist concept of primitive communism.
What production trait existed in tribal groups that were controlled by charismatic leaders?
Control of labour

For his second album, Late Registration (2005), he collaborated with film score composer Jon Brion and drew influence from non-rap influences such as English trip hop group Portishead. Blending West's primary soulful hip hop production with Brion's elaborate chamber pop orchestration, the album experimentally incorporated a wide array of different genres and prominent orchestral elements, including string arrangements, piano chords, brass flecks, and horn riffs among other symphonic instrumentation. It also incorporated a myriad of foreign and vintage instruments not typical in popular music, let alone hip hop, such as a celesta, harpsichord, Chamberlin, CS-80 analog synthesizer, Chinese bells and berimbau, vibraphones, and marimba. Rolling Stone described Late Registration as West claiming "the whole world of music as hip-hop turf" chronicling the album as "his mad quest to explode every cliché about hip-hop identity." Critic Robert Christgau wrote that "there's never been hip-hop so complex and subtle musically." For a period of time, Kanye West stood as the sole current pop star to tour with a string section, as audible on his 2006 live album Late Orchestration.
What composer did Kanye collaborate with for his second record?
Jon Brion
