Sun-drenched hip-hop dipped in vintage reggae and dub. Warm analog textures and thoughtful storytelling for long drives and summer afternoons.
Astronomy Class sounds like a humid afternoon in Sydney where the salt air meets the smell of old vinyl. It is hip-hop that has been left out in the sun long enough to soak up the rhythmic DNA of reggae and dub. The production is thick and tactile, favoring the round thump of an upright bass and the hiss of tape over sterile digital clicks. It feels lived-in, comfortable, and deeply rooted in a global crate-digging culture.
What sets them apart is the synergy between Ozi Batla's grounded, conversational flow and the production team's obsession with analog warmth. While many of their peers lean into aggressive boom-bap, this trio explores the 'resinous lens' of dub, using space and delay to let the songs breathe. Their later work even incorporates psychedelic Cambodian pop samples, creating a unique sonic bridge between Australian street poetry and Southeast Asian history.
Start with 'Mekong Delta Sunrise' if you want to hear their most ambitious sample-flipping, or 'Exit Strategy' for the foundational blend of reggae-rhythms and classic Aussie hip-hop storytelling. It is music for people who appreciate the craft of a well-placed snare and a lyric that actually has something to say.
