Background: Hunter was born in New York City, the son of Gertrude (nee Gelien) and Charles Kelm. His mother, from Hamburg, was a German Roman Catholic immigrant, and his father was Jewish. Hunter's father was reportedly abusive, and within a few years of his birth, his parents divorced. Tab grew up in California with his mother, older brother Walter, and maternal grandparents, John Henry and Ida (nee Sonnenfleth)
Context: Hunter had a 1957 hit record with the song "Young Love," which was No. 1 on the Billboard Hot 100 chart for six weeks (seven weeks on the UK Chart) and became one of the larger hits of the Rock 'n' Roll era. It sold over one million copies, and was awarded a gold disc by the RIAA.  He had the hit, "Ninety-Nine Ways," which peaked at No. 11 in the US and No. 5 in the UK. His success prompted Jack L. Warner to enforce the actor's contract with the Warner Bros. studio by banning Dot Records, the label for which Hunter had recorded the single (and which was owned by rival Paramount Pictures), from releasing a follow-up album he had recorded for them. He established Warner Bros. Records specifically for Hunter.  Hunter's acting career was also at its zenith. William Wellman used him again in a war film, Lafayette Escadrille (1958). Columbia Pictures borrowed him for a Western, Gunman's Walk (1958), a film that Hunter considers his favorite role.  Hunter starred in the 1958 musical film Damn Yankees, in which he played Joe Hardy of Washington, D.C.'s American League baseball club. The film had originally been a Broadway show, but Hunter was the only one in the film version who had not appeared in the original cast. The show was based on the 1954 best-selling book The Year the Yankees Lost the Pennant by Douglass Wallop. Hunter later said the filming was hellish because director George Abbott was only interested in recreating the stage version word for word.  He also starred in They Came to Cordura (1959), with Gary Cooper and Rita Hayworth. Sidney Lumet starred him opposite Sophia Loren in That Kind of Woman (1959).
Question: Did he have any albums?
Answer: 

Background: Plains Indians, Interior Plains Indians or Indigenous people of the Great Plains and Canadian Prairies are the Native American tribes and First Nation band governments who have traditionally lived on the greater Interior Plains (i.e. the Great Plains and the Canadian Prairies) in North America. Their historic nomadic culture and development of equestrian culture and resistance to domination by the government and military forces of Canada and the United States have made the Plains Indian culture groups an archetype in literature and art for American Indians everywhere. Plains Indians are usually divided into two broad classifications which overlap to some degree. The first group became a fully nomadic horse culture during the 18th and 19th centuries, following the vast herds of buffalo, although some tribes occasionally engaged in agriculture.
Context: The earliest Spanish explorers in the 16th century did not find the Plains Indians especially warlike. The Wichita in Kansas and Oklahoma lived in dispersed settlements with no defensive works. The Spanish initially had friendly contacts with the Apache (Querechos) in the Texas Panhandle.  Three factors led to a growing importance of warfare in Plains Indian culture. First, was the Spanish colonization of New Mexico which stimulated raids and counter-raids by Spaniards and Indians for goods and slaves. Second, was the contact of the Indians with French fur traders which increased rivalry among Indian tribes to control trade and trade routes. Third, was the acquisition of the horse and the greater mobility it afforded the Plains Indians. What evolved among the Plains Indians from the 17th to the late 19th century was warfare as both a means of livelihood and a sport.  The Plains Indians raided each other, the Spanish colonies, and, increasingly, the encroaching frontier of the Anglos for horses, and other property. They acquired guns and other European goods primarily by trade. Their principal trading products were buffalo hides and beaver pelts.  Although they could be tenacious in defense, Plains Indians warriors took the offensive mostly for material gain and individual prestige. The highest military honors were for "counting coup"--touching a live enemy. Battles between Indians often consisted of opposing warriors demonstrating their bravery rather than attempting to achieve concrete military objectives. The emphasis was on ambush and hit and run actions rather than closing with an enemy. Success was often counted by the number of horses or property obtained in the raid. Casualties were usually light. "Indians consider it foolhardiness to make an attack where it is certain some of them will be killed."  Due to their mobility, endurance, horsemanship, and knowledge of the vast plains that were their domain, the Plains Indians were often victors in their battles against the U.S. army in the American era from 1803 to about 1890. However, although Indians won many battles, they could not undertake lengthy campaigns. Indian armies could only be assembled for brief periods of time as warriors also had to hunt for food for their families. The exception to that was raids into Mexico by the Comanche and their allies in which the raiders often subsisted for months off the riches of Mexican haciendas and settlements. The basic weapon of the Indian warrior was the short, stout bow, designed for use on horseback and deadly, but only at short range. Guns were usually in short supply and ammunition scarce for Native warriors.
Question: and the third factor was?
Answer:
the acquisition of the horse and the greater mobility it afforded the Plains Indians.
