The Anti-Teleological Rock Combo (HR) is a contemporary chamber ensemble featuring four Zagreb-based instrumentalists who, although stemming from different backgrounds - classical, rock, jazz, experimental, and electronic music - share an equal interest in group improvisation and intergeneric approaches to musical composition: Luka Čapeta and Pavle Jovanović on electric guitars, Šimun Matišić on drums and assorted objects, and Leo Beslać on electric bass and flute, who himself prefers being referred to as the group’s ideologue rather than its principal composer or spiritus movens. Initially conceived as a vehicle for the development of a common improvisational language derived from predetermined pitch-class sets within the stylistic idiom of a guitar-oriented rock quartet, the group has since adopted a wider range of compositional and improvisational methods, seeking to expand the dynamic, textural, and timbral possibilities of what is generally perceived as a fairly limited and thoroughly explored musical unit. Graphic scores, gesticular notation, and game theory are just some of the devices utilised by the group to achieve and improve on its ever-evolving musical vocabulary. The group’s first LP, titled Motorcycle Rallies of the Third Kind, addresses this presumption in a way deliberately detached from any notion of either theory or discourse, preferring to remain firmly within the domain of aphoristic expression and plain silliness. It is due to be published through Kopaton Records in May 2024.
