This paper describes the disorienting aesthetics of some environments that are characteristic of the Anthropocene. We refer to these environments as 'mashed-up' and present three dimensions - phenomenological, epistemological and narrative - of the aesthetic disorientation they can trigger. We then advance the suggestion that a rich, nuanced and meaningful aesthetic experience of mashed-up Anthropocene environments (MAEs) calls for a mode of appreciation grounded on performative practices of aesthetic familiarisation with particular MAEs and entities and processes thereof. Familiarisation with MAEs, (...) we further note, can have disorienting codas of its own. It can reveal and highlight, rather than eliminate or alleviate, the solid strangeness of Earth even in the systemically humanised world of the Anthropocene, and it can expose and tie at least some of our agency, identity and sources of meaning in life to the same unstable evolvability of particular MAEs.
