The Lena (Russian: Ле́на, IPA: [ˈlʲenə]; Sakha: Өлүөнэ, Ölüöne) is the easternmost of the three great Siberian rivers that flow into the Arctic Ocean (the other two being the Ob River and the Yenisei River). It is the 11th longest river in the world and has the 9th largest watershed. It is the greatest river whose watershed is entirely within national ranges of Russia.

Rising at the height of 1,640 metres (5,381 ft) at its source Baikal Mountains south of the Central Siberian Plateau, 7 kilometres (4 mi) west of Lake Baikal, the Lena flows northeast, being joined by the Kirenga River, Vitim River and Olyokma River. From Yakutsk it enters the lowlands and flows north until joined by its right-hand affluent the Aldan River. The Verkhoyansk Range deflects it to the north-west; then, after receiving its most important left-hand tributary, the Vilyuy River, it makes its way nearly due north to the Laptev Sea, a division of the Arctic Ocean, emptying south-west of the New Siberian Islands by the Lena Delta - 30,000 square kilometres (11,583 sq mi) in area, and traversed by seven principal branches, the most important being Bykov, farthest east.

Lena Mary Calhoun Horne (June 30, 1917 – May 9, 2010) was an American singer, actress, civil rights activist and dancer.

Horne joined the chorus of the Cotton Club at the age of sixteen and became a nightclub performer before moving to Hollywood, where she had small parts in numerous movies, and more substantial parts in the films Cabin in the Sky and Stormy Weather. Due to the Red Scare and her left-leaning political views, Horne found herself blacklisted and unable to get work in Hollywood.

Returning to her roots as a nightclub performer, Horne took part in the March on Washington in August 1963, and continued to work as a performer, both in nightclubs and on television, while releasing well-received record albums. She announced her retirement in March 1980, but the next year starred in a one-woman show, Lena Horne: The Lady and Her Music, which ran for more than three hundred performances on Broadway and earned her numerous awards and accolades. She continued recording and performing sporadically into the 1990s, disappearing from the public eye in 2000.

Joni Mitchell, CC (born Roberta Joan Anderson; November 7, 1943) is a Canadian musician, singer songwriter, and painter. Mitchell began singing in small nightclubs in Saskatchewan and Western Canada and then busking in the streets and dives of Toronto. In 1965 she moved to the United States and, touring constantly, began to be recognized when her original songs ("Urge for Going," "Chelsea Morning," "Both Sides, Now," "The Circle Game") were covered by notable folk singers, allowing her to sign with Reprise Records and record her own debut album in 1968. Settling in Southern California, Mitchell and her popular songs like "Big Yellow Taxi" and "Woodstock" helped define an era and a generation. Her more starkly personal 1971 recording Blue has been called one of the best albums ever made. Musically restless, Mitchell switched labels and began moving toward jazz rhythms by way of lush pop textures on 1974's Court and Spark, her best-selling LP, featuring her radio hits "Help Me" and "Free Man in Paris."
