input: 1976's Black Market album was perhaps the most rock-oriented work which the group had produced to date. Weather Report's music had evolved further from open-ended funk jams into more melody-oriented, concise forms, which also offered a greater mass-market appeal. Zawinul further consolidated his use of keyboard synthesizers, while Shorter experimented with an early form of wind synthesizer, the Lyricon.  However, the album was recorded during yet another period of change for the group, with multiple personnel shuffles. Although Alyrio Lima played percussion on one track, he was replaced during the sessions by Don Alias (his first appearance with the group since the debut album debacle) and by Alex Acuna (a Peruvian drummer and conga player based in Las Vegas, who had played with Elvis Presley and Ike Turner, among others). Alphonso Johnson was also worn out from the strain put on the rhythm by the band's frequent changes of drummer. During a break in activity halfway through the recording of Black Market, Johnson opted to leave Weather Report to play with the Billy Cobham/George Duke Band (which featured a young John Scofield on guitar).  Prior to his departure, Johnson played on all but two of the new album's tracks. His replacement was Jaco Pastorius, a virtuoso fretless bass guitarist from Florida, who had been in touch with Zawinul for several years, and who came in to play on "Cannon Ball" and his own composition "Barbary Coast". Zawinul and Shorter had assumed that Chester Thompson would be departing alongside his friend Johnson, and for the second set of sessions they replaced him (on Jaco Pastorius' recommendation) with the former Mahavishnu Orchestra drummer Narada Michael Walden. Although Walden played on several album tracks, he ultimately proved unsuitable. Thompson returned for the final Black Market sessions, but left again after failing to gel as a rhythm section with Pastorius (whose style was much busier than that of Johnson). Thompson subsequently joined Genesis as their touring drummer.  Black Market continued Weather Report's ongoing run of success, selling well and being the fourth of the band's albums to win the album of the year award from Down Beat magazine. For the subsequent tour, Alex Acuna moved from percussion to the drum kit, and Don Alias was replaced by the young Puerto Rican percussionist Manolo Badrena, who had previously played with various Latin rock bands and with Art Blakey. The band made a very well-received appearance at the Montreux Jazz Festival, which was filmed for future release.

Question: Theodore Roosevelt Jr. ( ROH-z@-velt; October 27, 1858 - January 6, 1919) was an American statesman and writer who served as the 26th President of the United States from 1901 to 1909. He also served as the 25th Vice President of the United States from March to September 1901 and as the 33rd Governor of New York from 1899 to 1900. As a leader of the Republican Party during this time, he became a driving force for the Progressive Era in the United States in the early 20th century. His face is depicted on Mount Rushmore, alongside those of George Washington, Thomas Jefferson, and Abraham Lincoln.

Theodore Roosevelt Jr. was born on October 27, 1858, at East 20th Street in New York City. He was the second of four children born to socialite Martha Stewart "Mittie" Bulloch and businessman and philanthropist Theodore Roosevelt Sr. He had an older sister, Anna (nicknamed "Bamie"), a younger brother, Elliott, and a younger sister, Corinne. Elliott was later the father of First Lady Anna Eleanor Roosevelt, the wife of Theodore's distant cousin, President Franklin Delano Roosevelt. His paternal grandfather was of Dutch descent; his other ancestry included primarily Scottish and Scots-Irish, English and smaller amounts of German, Welsh, and French. Theodore Sr. was the fifth son of businessman Cornelius Van Schaack "C.V.S." Roosevelt and Margaret Barnhill. Theodore's fourth cousin, James Roosevelt I, who was also a businessman, was the father of President Franklin Delano Roosevelt. Mittie was the younger daughter of Major James Stephens Bulloch and Martha P. "Patsy" Stewart. Through the Van Schaacks, Roosevelt was a descendant of the Schuyler family.  Roosevelt's youth was largely shaped by his poor health and debilitating asthma. He repeatedly experienced sudden nighttime asthma attacks that caused the experience of being smothered to death, which terrified both Theodore and his parents. Doctors had no cure. Nevertheless, he was energetic and mischievously inquisitive. His lifelong interest in zoology began at age seven when he saw a dead seal at a local market; after obtaining the seal's head, Roosevelt and two cousins formed what they called the "Roosevelt Museum of Natural History". Having learned the rudiments of taxidermy, he filled his makeshift museum with animals that he killed or caught; he then studied the animals and prepared them for display. At age nine, he recorded his observation of insects in a paper entitled "The Natural History of Insects".  Roosevelt's father significantly influenced him. His father was a prominent leader in New York's cultural affairs; he helped to found the Metropolitan Museum of Art, and had been especially active in mobilizing support for the Union during the Civil War, even though his in-laws included Confederate leaders. Roosevelt said, "My father, Theodore Roosevelt, was the best man I ever knew. He combined strength and courage with gentleness, tenderness, and great unselfishness. He would not tolerate in us children selfishness or cruelty, idleness, cowardice, or untruthfulness." Family trips abroad, including tours of Europe in 1869 and 1870, and Egypt in 1872, shaped his cosmopolitan perspective. Hiking with his family in the Alps in 1869, Roosevelt found that he could keep pace with his father. He had discovered the significant benefits of physical exertion to minimize his asthma and bolster his spirits. Roosevelt began a heavy regime of exercise. After being manhandled by two older boys on a camping trip, he found a boxing coach to teach him to fight and strengthen his body.
