Lower Egypt (Arabic: الدلتا‎ al-Diltā) is the northern-most section of Egypt. It refers to the fertile Nile Delta region, which stretches from the area between Upper Egypt and the Mediterranean Sea — from El-Aiyat south of modern-day Cairo, and Zawyet Dahshur.

Today there are two principal channels that the Nile takes through the river's delta: one in the west at Rashid and one in the east at Damietta.

In ancient times, Pliny the Elder (N.H. 5.11) said that upon reaching the delta the Nile split into seven branches (from east to west): the Pelusiac, the Tanitic, the Mendesian, the Phatnitic, the Sebennytic, the Bolbitine, and the Canopic. Today the delta region is well watered, crisscrossed by channels and canals.

The climate in Lower Egypt is milder than that of Upper Egypt owing primarily to its proximity to the Mediterranean Sea. Temperatures are less extreme and rainfall is more abundant.

Lower Egypt was known as Ta-Mehu which means "land of papyrus." It was divided into twenty districts called nomes, the first of which was at el-Lisht. Because Lower Egypt was mostly undeveloped scrubland, undeveloped for human life and filled with all types of plant life such as grasses and herbs, the organization of the nomes underwent several changes.

Egypt ⁱ/ˈiːdʒɪpt/ (Arabic: مصر, Miṣr, Egyptian Arabic: [mɑsˤɾ] ; Coptic: Ⲭⲏⲙⲓ, Kīmi ; Sahidic Coptic: ⲕⲏⲙⲉ, Kēme), officially the Arab Republic of Egypt, Arabic:  جمهوريّة مصر العربيّة (help·info), is a country mainly in North Africa, with the Sinai Peninsula forming a land bridge in Southwest Asia. Egypt is thus a transcontinental country, and a major power in Africa, the Mediterranean Basin, the Middle East and the Muslim world. Covering an area of about 1,010,000 square kilometers (390,000 sq mi), Egypt is bordered by the Mediterranean Sea to the north, the Gaza Strip and Israel to the northeast, the Red Sea to the east, Sudan to the south and Libya to the west.

Egypt is one of the most populous countries in Africa and the Middle East. The great majority of its over 81 million people live near the banks of the Nile River, in an area of about 40,000 square kilometers (15,000 sq mi), where the only arable land is found. The large areas of the Sahara Desert are sparsely inhabited. About half of Egypt's residents live in urban areas, with most spread across the densely populated centres of greater Cairo, Alexandria and other major cities in the Nile Delta.

Pharoah Sanders (born October 13, 1940) is a Grammy Award–winning American jazz saxophonist.

Saxophonist Ornette Coleman once described him as "probably the best tenor player in the world." Emerging from John Coltrane's groups of the mid-1960s Sanders is known for his overblowing, harmonic, and multiphonic techniques on the saxophone, as well as his use of "sheets of sound." Sanders is an important figure in the development of free jazz; Albert Ayler famously said: "Trane was the Father, Pharoah was the Son, I am the Holy Ghost."

Born Ferrell Sanders in Little Rock, Arkansas, he began his professional career playing tenor saxophone in Oakland, California. He moved to New York City in 1961 after playing with rhythm and blues bands. He received his nickname "Pharoah" from bandleader Sun Ra, with whom he was performing. After moving to New York, Sanders had been destitute: "[H]e was often living on the streets, under stairs, where ever he could find to stay, his clothes in tatters. Sun Ra gave him a place to stay, bought him a new pair of green pants with yellow stripes (which Sanders hated but had to have), encouraged him to use the name 'Pharoah', and gradually worked him into the band."

Albert Ayler (July 13, 1936 – November 25, 1970) was an American avant-garde jazz saxophonist, singer and composer.

Ayler was among the most primal of the free jazz musicians of the 1960s; critic John Litweiler wrote that "never before or since has there been such naked aggression in jazz" He possessed a deep blistering tone—achieved by using the stiff plastic Fibrecane no. 4 reeds on his tenor saxophone—and used a broad, pathos-filled vibrato.

His trio and quartet records of 1964, like Spiritual Unity and The Hilversum Session, show him advancing the improvisational notions of John Coltrane and Ornette Coleman into abstract realms where whole timbre, and not just mainly harmony with melody, is the music's backbone. His ecstatic music of 1965 and 1966, like "Spirits Rejoice" and "Truth Is Marching In" has been compared by critics to the sound of a brass band, and involved simple, march-like themes which alternated with wild group improvisations and were regarded as retrieving jazz's pre-Louis Armstrong roots.

Warren Harding "Sonny" Sharrock (August 27, 1940 – May 26, 1994) was an American jazz guitarist. He was once married to singer Linda Sharrock, with whom he sometimes recorded and performed.

One of few guitarists in the first wave of free jazz in the 1960s, Sharrock was known for his incisive, heavily chorded attack, his highly-amplified bursts of wild feedback, and for his use of saxophone-like lines played loudly on guitar.

Sharrock began his musical career singing doo wop in his teen years. He collaborated with Pharoah Sanders and Alexander Solla in the late 1960s, appearing first on Sanders's 1966 effort, Tauhid. He made several appearances with flautist Herbie Mann and also made an uncredited guest appearance on Miles Davis's A Tribute to Jack Johnson, perhaps his most famous cameo.

He had in fact wanted to play tenor saxophone from his youth after hearing John Coltrane play on Davis's album Kind of Blue on the radio at age 19, but his asthma prevented this from happening. Sharrock said repeatedly, however, that he still considered himself "a horn player with a really fucked up axe."
