Shchi (Russian: щи, pronounced [ɕːi]) is a Russian soup with cabbage as the primary ingredient. Its primary distinction is its sour taste, which usually originates from cabbage. When sauerkraut is used instead, the soup is called sour shchi, and soups based on sorrel, spinach, nettle, and similar plants are called green shchi (Russian: зелёные щи, zelyoniye shchi). In the past, the term sour shchi was also used to refer to a drink, a variation of kvass, which was unrelated to the soup.

Shchi is a traditional soup of Russia where it has been known as far back as the 9th century, soon after cabbage was introduced from Byzantium. Its popularity in Russia originates from several factors. Shchi is relatively easy to prepare; it can be cooked with or without various types of meat that makes it compatible with different religions; and it can be frozen and carried as a solid on a trip to be cut up when needed. Finally, it was noticed that most people do not get sick of shchi and can eat it daily. This property is referenced in the Russian saying: "Pодной отец надоест, а щи – никогда!" (Rodnoi otets nadoyest, a shchi--nikogda! "One may tire of one's own father, but never of shchi!"). As a result, by the 10th century shchi became a staple food of Russia, and another popular saying sprang from this fact: "Щи да каша – пища наша." (Shchi da kasha - pishcha nasha "Shchi and kasha are our staples"). The major components of shchi were originally cabbage, meat (beef, pork, lamb, or poultry), mushrooms, flour, and spices (based on onion and garlic). Cabbage and meat were cooked separately and smetana was added as a garnish before serving. Shchi is traditionally eaten with rye bread.

Elvis Aaron Presley (January 8, 1935 – August 16, 1977) was one of the most popular American singers of the 20th century. A cultural icon, he is widely known by the single name Elvis. He is often referred to as the "King of Rock and Roll" or simply "the King".

Born in Tupelo, Mississippi, Presley moved to Memphis, Tennessee, with his family at the age of 13. He began his career there in 1954, working with Sun Records owner Sam Phillips, who wanted to bring the sound of African American music to a wider audience. Accompanied by guitarist Scotty Moore and bassist Bill Black, Presley was the most important popularizer of rockabilly, an uptempo, backbeat-driven fusion of country and rhythm and blues. RCA Victor acquired his contract in a deal arranged by Colonel Tom Parker, who would manage the singer for over two decades. Presley's first RCA single, "Heartbreak Hotel", released in January 1956, was a number one hit. He became the leading figure of the newly popular sound of rock and roll with a series of network television appearances and chart-topping records. His energized interpretations of songs, many from African American sources, and his uninhibited performance style made him enormously popular—and controversial. In November 1956, he made his film debut in Love Me Tender.

James Marshall "Jimi" Hendrix (born Johnny Allen Hendrix; November 27, 1942 – September 18, 1970) was an American musician and singer-songwriter. He is widely considered to be the greatest electric guitarist in music history, and one of the most influential musicians of his era despite mainstream exposure limited to just three years. After initial success in Europe with his group The Jimi Hendrix Experience, he achieved fame in the United States following his 1967 performance at the Monterey Pop Festival. Later, he headlined the iconic 1969 Woodstock Festival and the 1970 Isle of Wight Festival. He often favored raw overdriven amplifiers with high gain and treble and helped develop the previously undesirable technique of guitar amplifier feedback.

Hendrix helped to popularize use of the wah-wah pedal in mainstream rock, which he often used to deliver tonal exaggerations in his solos, particularly with high bends, complex guitar playing, and use of legato. As a record producer, he also broke new ground in using the recording studio as an extension of his musical ideas. He was one of the first to experiment with stereophonic phasing effects for rock recording.^{[citation needed]} He was influenced by blues artists such as B.B. King, Muddy Waters, Howlin' Wolf, Albert King and Elmore James,rhythm and blues and soul guitarists Curtis Mayfield and Steve Cropper, and the jazz guitarist Wes Montgomery. Hendrix began dressing and wearing a moustache like Little Richard when he performed and recorded in his band from March 1, 1964 through to the spring of 1965. In 1966, he stated, "I want to do with my guitar what Little Richard does with his voice".
