Trouser Press opined that the EP was "practically unmatched in its day. Nothing sounded like this in 1979. Circle X caught the tail end of the no wavescene and out-waved it with a mere four ear-splitting compositions."
Re-issues
Circle X was later re-issued on CD in 1996 through label Dexter's Cigar. It was re-issued on 12" vinyl in Germany in 2009 through label Insolito.
