The term black people is used in some socially-based systems of racial classification for humans of a dark-skinned phenotype, relative to other racial groups represented in a particular social context. Different societies apply different criteria regarding who is classified as "black", and often social variables such as class and socio-economic status also play a role, so that relatively dark-skinned people can be classified as white if they fulfill other social criteria of "whiteness" and relatively light-skinned people can be classified as black if they fulfill the social criteria for "blackness" in a particular setting.

As a biological phenotype being "black" is often associated with the very dark skin colors of some people who are classified as "black". But, particularly in the United States, the racial or ethnic classification also refers to people with all possible kinds of skin pigmentation from the darkest through to the very lightest skin colors, including albinos, if they are believed by others to have African ancestry, or to exhibit cultural traits associated with being "African-American". As a result, in the United States the term "black people" is not an indicator of skin color but of socially based racial classification.

Regina Ilyinichna Spektor (Russian: Реги́нa Ильи́нична Спе́ктор, IPA: [rʲɪˈɡʲinə ˈspʲɛktər], English: /rɨˈdʒiːnə ˈspɛktər/; born February 18, 1980) is an American singer-songwriter and pianist. Her music is associated with the anti-folk scene centered in New York City's East Village.

Spektor was born in Moscow, Soviet Union in 1980 to a musical Russian Jewish family. Her father, Ilya Spektor, is a photographer and amateur violinist. Her mother, Bella Spektor, was a music professor in a Soviet college of music and now teaches at a public elementary school in Mount Vernon, New York. She has a brother Barry (Bear), who was featured in track 7, "* * *", or "Whisper", of her 2004 album, Soviet Kitsch.

She learned how to play piano by practising on a Petrof upright that was given to her mother by her grandfather. She was also exposed to the music of rock and roll bands such as The Beatles, Queen, and The Moody Blues by her father, who obtained such recordings in Eastern Europe and traded cassettes with friends in the Soviet Union. The family left the Soviet Union in 1989, when Regina was nine and a half, during the period of Perestroika, when Soviet citizens were permitted to emigrate. Regina had to leave her piano behind. The seriousness of her piano studies led her parents to consider not leaving the USSR, but they finally decided to emigrate, due to the ethnic and political discrimination that Jews faced. Spektor is fluent in Russian and reads Hebrew, and has since paid tribute to her Russian heritage, quoting the poem February by the Russian poet Boris Pasternak in her song Après Moi, and stating “I’m very connected to the language and the culture.”
