Abstracthiphop is an experimental genre that uses a variety of techniques to produce its sounds and lyrics. It is often considered a progressive form of hip hop and can be seen as an alternative to mainstream hip hop music.
Abstract artists tend to focus on more abstract ideas such as existentialism or social institutions rather than everyday problems or braggadocio. They also usually avoid the more upfront, visceral language of typical hip hop and instead prefer extensive metaphors and symbolic word choice.
Abstract hip hop is typically characterized by unconventional beats that are akin in style to experimental hip hop. They can also be a combination of electronic and acoustic styles, with the latter favored by many abstract rappers.
Abstract rappers often experiment with sound design, utilizing sudden cut-offs or abruptly changing tempos to create a unique feel. They may also use sampled samples, such as instrumentals from jazz or funk music.
Artists who specialize in abstract rap may also include spoken word elements into their lyrical style. This can be done through use of rhyme schemes or through lyrical flow.
One of the most interesting and provocative artists in this genre is Earl Sweatshirt. His album Some Rap Songs is filled with emotional depth and is highly experimental in nature. He incorporates a lot of jazz samples in his songs which creates an avant-garde sound.
