The Ditch Trilogy refers to a trio of rock music albums by Neil Young made in the wake of his chart-topping best-seller, Harvest. The moniker derives from a quote by Young, printed in the self-penned track-by-track liner notes to his career summary compilation Decade of 1977. In the text about the only #1 single of his life, "Heart of Gold," Young states: "This song put me in the middle of the road. Travelling there soon became a bore so I headed for the ditch. A rougher ride but I saw more interesting people there."

After his success with Crosby, Stills, Nash & Young and Harvest, Young took an abrupt artistic turn with the soundtrack and film Journey Through the Past. His next three albums cemented this move. Much of this work is characterized by loose, almost "sloppy" playing, a type of performance which Young encouraged. Lyrical themes from this time include the hollowness of show business and commercial success ("LA" from Time Fades Away), the toll exacted by hard drug use, specifically the heroin-related deaths of former Crazy Horse guitarist Danny Whitten and roadie Bruce Berry (the title track of Tonight's the Night), and other, less specific but still downbeat subject matter.

Neil Percival Young,OC,OM (born November 12, 1945) is a Canadian singer-songwriter who is widely regarded as one of the most influential musicians of his generation.

Young began performing as a solo artist in Canada in 1960, before moving to California in 1966, where he co-founded the band Buffalo Springfield along with Stephen Stills and Richie Furay, and later joined Crosby, Stills & Nash as a fourth member in 1969. He forged a successful and acclaimed solo career, releasing his first album in 1968; his career has since spanned over 40 years and 34 studio albums, with a continual and uncompromising exploration of musical styles. The Rock and Roll Hall of Fame website describes Young as "one of rock and roll’s greatest songwriters and performers". He has been inducted into the Hall of Fame twice: first as a solo artist in 1995, and second as a member of Buffalo Springfield in 1997.

Young's work is characterized by his distinctive guitar work, deeply personal lyrics and signature alto or high tenor singing voice. Although he accompanies himself on several different instruments, including piano and harmonica, his idiosyncratic electric and clawhammer acoustic guitar playing are the defining characteristics of a varyingly ragged and melodic sound. While Young has experimented with differing music styles, including swing and electronic music throughout a varied career, his best known work usually falls into two primary styles: acoustic (folk and country rock) and electric (amplified hard rock, very often in collaboration with the band Crazy Horse). Young has also adopted elements from newer styles such as alternative rock and grunge. His influence on the latter caused some to dub him the "Godfather of Grunge".

Crazy Horse (Lakota: Tȟašúŋke Witkó (in Standard Lakota Orthography), literally "His-Horse-Is-Crazy" or "His-Horse-Is-Spirited"; ca. 1840 – September 5, 1877) was a Native American war leader of the Oglala Lakota. He took up arms against the U.S. Federal government to fight against encroachments on the territories and way of life of the Lakota people, including leading a war party at the Battle of the Little Bighorn in June 1876.

After surrendering to U.S. troops under General Crook in 1877, Crazy Horse was fatally wounded by a military guard while allegedly resisting imprisonment at Camp Robinson in present-day Nebraska. He ranks among the most notable and iconic of Native American tribal members and has been honored by the U.S. Postal Service with a 13¢ Great Americans series postage stamp.

Sources differ on the precise year of Crazy Horse's birth, but they agree he was born between 1840 and 1845. According to a close friend, he and Crazy Horse "were both born in the same year at the same season of the year", which census records and other interviews place at about 1845.Encouraging Bear, an Oglala medicine man and spiritual adviser to the Oglala war leader, reported that Crazy Horse was born "in the year in which the band to which he belonged, the Oglala, stole One Hundred Horses, and in the fall of the year", a reference to the annual Lakota calendar or winter count. Among the Oglala winter counts, the stealing of 100 horses is noted by Cloud Shield, and possibly by American Horse and Red Horse owner, as equivalent to the year 1840-41. Oral history accounts from relatives on the Cheyenne River Reservation place his birth in the spring of 1840. On the evening of his son's death, the elder Crazy Horse told Lieutenant H. R. Lemly that his son "would soon have been thirty-seven, having been born on the South Cheyenne river in the fall of 1840".
