The Obelisk recently called it "cosmic grunge." Recyclable Sounds calls it "traditionalist post-Hawkwind moto-space rock." Give whatever name you want to their sound, they've never played by any rules.
In the year prior to releasing their debut album, Seismic Vibes, they performed at Meltasia, Indian Summer, SX Stoner Jam, Stoner Daze, SXSW, Desert Daze SXSW Showcase, and embarked on two US tours. In the year that followed, they went on another run to Texas, supported heavy psych juggernauts Ruby the Hatchet and The Well, Division Brewing released a Sun Voyager Double IPA, and they solidified spots on the inaugural Desertfest NYC, Electric Funeral IV, and Descendants of Crom. "If you’re a connoisseur of the latest in fuzzed-out heavy music, Sun Voyager are a band that should have a place on your radar." - Decibel Magazine
