input: After the 12th century BCE, as the Rigveda had taken its final form, the Vedic society transitioned from semi-nomadic life to settled agriculture. Vedic culture extended into the western Ganges Plain. Possession of horses remained an important priority of Vedic leaders and a remnant of the nomadic lifestyle, resulting in trade routes beyond the Hindu Kush to maintain this supply as horses needed for cavalry and sacrifice could not be bred in India. The Gangetic plains had remained out of bounds to the Vedic tribes because of thick forest cover. After 1000 BCE, the use of iron axes and ploughs became widespread and the jungles could be cleared with ease. This enabled the Vedic Aryans to settle at the western Gangetic plains. Many of the old tribes coalesced to form larger political units.  The Vedic religion was further developed when the Indo-Aryans migrated into the Ganges Plain after c. 1100 BCE and became settled farmers, further syncretising with the native cultures of northern India. In this period the varna system emerged, state Kulke and Rothermund, which in this stage of Indian history were a "hierarchical order of estates which reflected a division of labor among various social classes". The Vedic period estates were four: Brahmin priests and warrior nobility stood on top, free peasants and traders were the third, and slaves, labourers and artisans, many belonging to the indigenous people, were the fourth. This was a period where agriculture, metal, and commodity production, as well as trade, greatly expanded, and the Vedic era texts including the early Upanishads and many Sutras important to later Hindu culture were completed.  The Kuru Kingdom, the earliest Vedic "state", was formed by a "super-tribe" which joined several tribes in a new unit. To govern this state, Vedic hymns were collected and transcribed, and new rituals were developed, which formed the now orthodox Shrauta rituals. Two key figures in this process of the development of the Kuru state were the king Parikshit and his successor Janamejaya, transforming this realm into the dominant political and cultural power of northern Iron Age India.  The most well-known of the new religious sacrifices that arose in this period were the Ashvamedha (horse sacrifice). This sacrifice involved setting a consecrated horse free to roam the kingdoms for a year. The horse was followed by a chosen band of warriors. The kingdoms and chiefdoms in which the horse wandered had to pay homage or prepare to battle the king to whom the horse belonged. This sacrifice put considerable pressure on inter-state relations in this era. This period saw also the beginning of the social stratification by the use of varna, the division of Vedic society in Kshatriya, Brahmins, Vaishya and Shudra.  The Kuru kingdom declined after its defeat by the non-Vedic Salva tribe, and the political centre of Vedic culture shifted east, into the Panchala kingdom on the Ganges. Later, the kingdom of Videha emerged as a political centre farther to the East, in what is today northern Bihar of India and south eastern Nepal, reaching its prominence under the king Janaka, whose court provided patronage for Brahmin sages and philosophers such as Yajnavalkya, Uddalaka Aruni, and Gargi Vachaknavi.

input: In September 1966, with no money to return to San Francisco, Big Brother signed a contract with Mainstream Records. They recorded four of the songs for the album Big Brother & the Holding Company in a studio in Chicago at the end of their four-week stint at Mother Blues on Wells Street. The club had paid them for only the first two weeks.' The remainder of the record was recorded in Los Angeles on December 12-14. Mainstream was known for its jazz records, and Big Brother was the first rock band to appear on the label. This may have influenced the final result, since the album sounded very different from what the band expected: acoustic and folk instead of heavy acid rock. The first single released was "Blind Man" b/w "All Is Loneliness," both from the album sessions, in July 1967. It was popular in the San Francisco Bay Area, but did not garner much national attention. A second single, "Down on Me" b/w "Call On Me" was released along with their self-titled debut album in August 1967, following the band's national success after the Monterey Pop Festival. The album debuted on Billboard charts on 9/2/67, peaking at No. 60. It stayed on the charts for a total of 30 weeks.  The Pop Chronicles criticized the record as difficult to find and "technically disappointing". "Down On Me" had a long gestation in the marketplace and finally debuted on the Billboard Hot 100 chart on 8/31/68, peaking at No. 43. It stayed on the charts for 8 weeks. Other singles from the album were released through the end of 1967 and 1968. One final Mainstream single, "Coo Coo" b/w "The Last Time," was released after the band's second album was issued by Columbia Records in November, 1968. These last songs were from the original album sessions, but were not included on the LP until Columbia acquired all of the band's Mainstream recordings and reissued the album in the 1970s.  The band then moved to Lagunitas, in Marin County, California, to a communal house. Later in 1967 they put an ad in the San Francisco Oracle with the apparent intention of moving back to the "City". The ad read: "Big Brother is returning to the city. Need rehearsal hall and a place to live. Write to B.B.& the H.C. at Box 94 Lagunitas."
