Some re-issues are blatant money-making efforts and others are a public service. Think of these two as the latter. They’re both on vinyl. No digital downloads.
Dismissing The Onyas as a sub-tropical, Johnny-come-lately version of the Cosmic Psychos does both bands a disservice. Both bands are still going (The Onyas sporadically) and share a member in John McKeering (aka Mad Macka). You might say him joining Cosmic Psychos was inevitable. Some have.
