The release of the Wolfmother EP began the consequently commonplace comparisons between the band and 1960s and 1970s rock artists, namely Black Sabbath. In a review for music website allmusic, critic Eduardo Rivadavia summarised the record by saying "Wolfmother aren't claiming any measure of originality here -- they're just offering a form of time travel." He also said the following in his review:
Powerfully fuzzy guitar riffs, serpentine basslines, thumping percussion, echoed, warbling vocals, and even the occasional Hammond organ provide the fundamental building blocks for the youthful trio's convincingly Jurassic creations; and the impressive opening tandem of "Dimension" [...] and "Woman" carry off the illusion so authentically [...]. Next number "Apple Tree" diverges from the basic template just a tad by interspersing a jolt of psychedelicgarage rock into its otherwise familiarly ponderous sections [...] and the grand finale intended by "The White Unicorn" is largely achieved thanks to surprisingly pretty, chiming guitar melodies à la Led Zeppelin.
Wolfmother's debut release was also a minor commercial success, reaching number 35 on the Australian ARIA Singles Chart.
