Life's Blood was an American hardcore punk band formed by four first-year college students in New York City in 1987.
It consisted of Adam Nathanson on guitars, Neil Burke on bass, John Kriksciun on drums, and Combined Effort all ages shows promoter and fanzine editor Jason O'Toole on vocals.
Life's Blood gained a loyal following for their aggressive sound that blended East Coast hardcore-punk with melodic Oi!, as well as their intelligent lyrics.
Burke, an artist who works in visual and audio mediums, played in Born Against, Sinking Body and Men's Recovery Project.
In 1992, O'Toole performed and recorded with Factory in a lineup including past and future members of Intent, Hail Mary, Brown Cuts Neighbors and Limp Wrist.
