Question: What is the name of the type of music that postulates that human beings have evolved to live in tribal society and was performed by Steve Tibbetts?

<P0-S0> Machine interpretation of documents and services in Semantic Web environment is primarily enabled by (a) the capability to mark documents, document segments and services with semantic tags and (b) the ability to establish contextual relations between the tags with a domain model, which is formally represented as ontology. <P0-S1>  Human beings use natural languages to communicate an abstract view of the world. <P0-S2>  Natural language constructs are symbolic representations of human experience and are close to the conceptual model that Semantic Web technologies deal with. <P0-S3>  Thus, natural language constructs have been naturally used to represent the ontology elements. <P0-S4>  This makes it convenient to apply Semantic Web technologies in the domain of textual information. <P0-S5>  In contrast, multimedia documents are perceptual recording of human experience. <P0-S6>  An attempt to use a conceptual model to interpret the perceptual records gets severely impaired by the semantic gap that exists between the perceptual media features and the conceptual world. <P0-S7>  Notably, the concepts have their roots in perceptual experience of human beings and the apparent disconnect between the conceptual and the perceptual world is rather artificial. <P0-S8>  The key to semantic processing of multimedia data lies in harmonizing the seemingly isolated conceptual and the perceptual worlds. <P0-S9>  Representation of the Domain knowledge needs to be extended to enable perceptual modeling, over and above conceptual modeling that is supported. <P0-S10>  The perceptual model of a domain primarily comprises observable media properties of the concepts. <P0-S11>  Such perceptual models are useful for semantic interpretation of media documents, just as the conceptual models help in the semantic interpretation of textual documents. <SEP> <P1-S0> Tibbetts plays acoustic and electric guitar as well as exotic percussive instruments such as the kendang and kalimba. <P1-S1>  His musical compositions span several genres and styles including experimental, jazz, rock, ambient, and world music. <P1-S2>  He has self described his music as "post modern neo-primitivism". <P1-S3>  Often more than one genre or style is found in a single composition. <P1-S4>  A variety of techniques may be used with the guitar such as a string-bending technique sonically imitating a sarangi with a 12-string guitar while also alternating between ambient soundscape and Hendrix-like distorted and feedbacked leads with an electric guitar. <P1-S5>  He incorporates field-recordings such as the footsteps in the track "Running" from "Safe Journey", or the chanting of Nepalese villagers from the last tracks of "Big Map Idea". <P1-S6>  Tibbetts' recordings often include percussion by St Paul's Marc Anderson. <SEP> <P2-S0> Neotribalism (a.k.a. neo-tribalism and modern tribalism) is a sociological concept which postulates that human beings have evolved to live in tribal society, as opposed to mass society, and thus will naturally form social networks constituting new "tribes". <SEP> <P3-S0> Narrative psychology is a perspective within psychology concerned with the "storied nature of human conduct", that is, how human beings deal with experience by observing stories and listening to the stories of others. <P3-S1>  Operating under the assumption that human activity and experience are filled with "meaning" and stories, rather than logical arguments or lawful formulations, narrative psychology is the study of how human beings construct stories to deal with experiences.
