Ex Input:
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.

Ex Output:
What composer did Kanye collaborate with for his second record?

Ex Input:
Beginning in 1939, Dr. Peter Goldmark and his staff at Columbia Records and at CBS Laboratories undertook efforts to address problems of recording and playing back narrow grooves and developing an inexpensive, reliable consumer playback system. It took about eight years of study, except when it was suspended because of World War II. Finally, the 12-inch (30 cm) Long Play (LP) 33 1⁄3 rpm microgroove record album was introduced by the Columbia Record Company at a New York press conference on June 18, 1948.

Ex Output:

What caused a delay in the production of high quality records?
