Problem: Background: Cream were a 1960s British rock power trio consisting of drummer Ginger Baker, guitarist/singer Eric Clapton and lead singer/bassist Jack Bruce. The group's third album, Wheels of Fire (1968), was the world's first platinum-selling double album. The band is widely regarded as the world's first successful supergroup. In their career, they sold more than 15 million copies of their albums worldwide.
Context: The band first visited the United States in March 1967 to play nine dates at the RKO 58th Street Theatre in New York. There was little impact, as impresario Murray the K placed them at the bottom of a six-act bill that performed three times per date, eventually reducing the band to one song per concert. They returned to record Disraeli Gears in New York between 11 May and 15 May 1967. This, the band's second album, was released in November 1967 and reached the Top 5 in the charts on both sides of the Atlantic. Produced by Felix Pappalardi (who later co-founded the Cream-influenced quartet Mountain) and engineer Tom Dowd, it was recorded at Atlantic Studios in New York. Disraeli Gears is often considered to be the band's defining effort, successfully blending psychedelic British rock with American blues.  In addition to "Strange Brew" and "Tales of Brave Ulysses", Disraeli Gears features "Sunshine of Your Love," which became the group's unofficial anthem. Bruce and Pete Brown came upon the idea in a state of near desperation in the wee hours. In a last-ditch attempt to salvage something from the long and fruitless night at his apartment, the bleary-eyed Bruce pulled out his double bass again and played a riff. At that point, Brown looked out the window and saw the sun was about to rise: "It's getting near dawn ...," he said to himself. Brown put the words on paper then thought some more: "When lights close their tired eyes".  The album was originally slated for release in the summer of 1967, but the record label opted to scrap the planned cover and repackage it with a new psychedelic cover, designed by artist Martin Sharp, and the resulting changes delayed its release for several months. The album was remarkable for the time, with a psychedelic design patterned over a publicity photo of the trio.  Although the album is considered one of Cream's finest efforts, it has never been well represented in the band's live sets. Although they consistently played "Tales of Brave Ulysses" and "Sunshine of Your Love," several songs from Disraeli Gears were quickly dropped from performances in mid-1967, favouring longer jams instead of short pop songs. "We're Going Wrong" was the only additional song from the album the group performed live. In fact, at their 2005 reunion shows in London, the band played only three songs from Disraeli Gears: "Outside Woman Blues", "We're Going Wrong," and "Sunshine of Your Love"; at their three October 2005 performances in New York, "Tales of Brave Ulysses" was also included in the setlist.  In August 1967, they played their first headlining dates in the US, playing first at The Fillmore in San Francisco and later at The Pinnacle in Los Angeles. The concerts were a great success and proved very influential on both the band itself and the flourishing hippie scene surrounding them. Upon discovering a growing listening audience, the band began to stretch out on stage, incorporating more time in their repertoire, some songs reaching jams of twenty minutes. Long, drawn-out jams in numbers like "Spoonful", "N.S.U.", "I'm So Glad", and "Sweet Wine" became live favourites, while songs like "Sunshine of Your Love", "Crossroads", and "Tales of Brave Ulysses" remained reasonably short.
Question: what was some of their signature songs?
Answer: Tales of Brave Ulysses" and "Sunshine of Your Love,

Background: Charles Parker Jr. (August 29, 1920 - March 12, 1955), also known as Yardbird and Bird, was an American jazz saxophonist and composer. Parker was a highly influential jazz soloist and a leading figure in the development of bebop, a form of jazz characterized by fast tempos, virtuosic technique and advanced harmonies. Parker was a blazingly fast virtuoso, and he introduced revolutionary harmonic ideas including rapid passing chords, new variants of altered chords, and chord substitutions. His tone ranged from clean and penetrating to sweet and somber.
Context: Parker's life was riddled with depression and heroin addiction. This addiction caused him to miss performances and be considered unemployable. He frequently resorted to busking, receiving loans from fellow musicians and admirers, and pawning his saxophones for drug money. Heroin use was rampant in the jazz scene, and users could acquire it with little difficulty.  Although he produced many brilliant recordings during this period, Parker's behavior became increasingly erratic. Heroin was difficult to obtain once he moved to California, where the drug was less abundant, so he used alcohol as a substitute. A recording for the Dial label from July 29, 1946, provides evidence of his condition. Before this session, Parker drank a quart of whiskey. According to the liner notes of Charlie Parker on Dial Volume 1, Parker missed most of the first two bars of his first chorus on the track, "Max Making Wax". When he finally did come in, he swayed wildly and once spun all the way around, away from his microphone. On the next tune, "Lover Man", producer Ross Russell physically supported Parker. On "Bebop" (the final track Parker recorded that evening) he begins a solo with a solid first eight bars; on his second eight bars, however, he begins to struggle, and a desperate Howard McGhee, the trumpeter on this session, shouts, "Blow!" at him. Charles Mingus considered this version of "Lover Man" to be among Parker's greatest recordings, despite its flaws. Nevertheless, Parker hated the recording and never forgave Ross Russell for releasing it. He re-recorded the tune in 1951 for Verve.  Parker's life took a turn for the worst when his 2 year old daughter tragically passed away from pneumonia. He attempted suicide twice in 1954, which landed him in a mental hospital.  When Parker received his discharge from the hospital, he was clean and healthy. Before leaving California, he recorded "Relaxin' at Camarillo" in reference to his hospital stay. He returned to New York, resumed his addiction to heroin and recorded dozens of sides for the Savoy and Dial labels, which remain some of the high points of his recorded output. Many of these were with his so-called "classic quintet" including Davis and Roach.
