input: Dr. Dre has said that his primary instrument in the studio is the Akai MPC3000, a drum machine and sampler, and that he often uses as many as four or five to produce a single recording. He cites 1970s funk musicians such as George Clinton, Isaac Hayes and Curtis Mayfield as his primary musical influences. Unlike most rap producers, he tries to avoid samples as much as possible, preferring to have studio musicians re-play pieces of music he wants to use, because it allows him more flexibility to change the pieces in rhythm and tempo. In 2001 he told Time magazine, "I may hear something I like on an old record that may inspire me, but I'd rather use musicians to re-create the sound or elaborate on it. I can control it better." Other equipment he uses include the E-mu SP-1200 drum machine and other keyboards from such manufacturers as Korg, Rhodes, Wurlitzer, Moog, and Roland. Dr. Dre also stresses the importance of equalizing drums properly, telling Scratch magazine in 2004 that he "used the same drum sounds on a couple of different songs on one album before but you'd never be able to tell the difference because of the EQ." Dr. Dre also uses the digital audio workstation Pro Tools and uses the software to combine hardware drum machines and vintage analog keyboards and synthesizers.  After founding Aftermath Entertainment in 1996, Dr. Dre took on producer Mel-Man as a co-producer, and his music took on a more synthesizer-based sound, using fewer vocal samples (as he had used on "Lil' Ghetto Boy" and "Let Me Ride" on The Chronic, for example). Mel-Man has not shared co-production credits with Dr. Dre since approximately 2002, but fellow Aftermath producer Focus has credited Mel-Man as a key architect of the signature Aftermath sound.  In 1999, Dr. Dre started working with Mike Elizondo, a bassist, guitarist, and keyboardist who has also produced, written and played on records for female singers such as Poe, Fiona Apple and Alanis Morissette, In the past few years Elizondo has since worked for many of Dr. Dre's productions. Dr. Dre also told Scratch magazine in a 2004 interview that he has been studying piano and music theory formally, and that a major goal is to accumulate enough musical theory to score movies. In the same interview he stated that he has collaborated with famed 1960s songwriter Burt Bacharach by sending him hip hop beats to play over, and hopes to have an in-person collaboration with him in the future.

Question: Robert Dale Owen (November 7, 1801 - June 24, 1877) was a Scottish-born social reformer who immigrated to the United States in 1825, became a U.S. citizen, and was active in Indiana politics as member of the Democratic Party in the Indiana House of Representatives (1835-39 and 1851-53) and represented Indiana in the U.S. House of Representatives (1843-47). As a member of Congress, Owen successfully pushed through the bill that established Smithsonian Institution and served on the Institution's first Board of Regents. Owen also served as a delegate to the Indiana Constitutional Convention in 1850 and was appointed as U.S. charge d'affaires (1853-58) to Naples. Owen was a knowledgeable exponent of the socialist doctrines of his father, Robert Owen, and managed the day-to-day operation of New Harmony, Indiana, the socialistic utopian community he helped establish with his father in 1825.

After his first term in the Indiana legislature and two unsuccessful campaigns for election to the U.S. Congress in 1838 and in 1840, Owen was elected as a Democrat to the U.S. House of Representatives in 1842. He served from 1843 to 1847 in the Twenty-eighth and Twenty-ninth Congresses. Owen was chairman of the Committee on Roads and Canals during the Twenty-eighth Congress. He was also involved in the debates about the annexation of Texas and an Oregon boundary dispute in 1844 that led to the establishment of the U.S-British boundary at the 49th parallel north, the result of the Oregon Treaty (1846).  While serving as a member of Congress, Owen introduced and helped to secure passage of the bill that founded the Smithsonian Institution in 1846. Owen was appointed to the Smithsonian Institution's first Board of Regents and chaired its Building Committee, which oversaw the construction of the Smithsonian Institution Building in Washington, D.C., and recommended James Renwick, Jr. as architect, James Dixson and Gilbert Cameron as the contractors, and the Seneca Quarry for its distinct, dark-red sandstone.  Owen, his brother David Dale Owen, and architect Robert Mills, were involved in developing preliminary plans for the Smithsonian Building. These early plans influenced Renwick's choice of the Romanesque Revival architectural style (sometimes referred to as Norman-style architecture) and his three-story design for the building, which was finally selected, although not without controversy. Owen's book Hints on Public Architecture (1849) argued the case for the suitability of Renwick's Romanesque Revival (Norman) architectural style for public buildings such as the Smithsonian "Castle," which he discussed in detail. Seven full-page illustrations and details of the building's architectural elements were prominently featured in the book, leading some to criticize Owen for his bias toward Renwick and his preference for Norman-style architecture over other popular styles.
