Marykate was born in a small town in New England and now lives in New York City. Since the mid-90's, Marykate has released six albums, a couple of .45’s; her music has been featured in movies and television shows; and she has played across the US and EU to big festival crowds and empty seats in darkened basements.
Marykate O'Neil's music has been called --- Elvis Costello meets Astrud Gilberto; a female George Harrison; a Capote-esque story teller; and most frequently like herself. The Boston Globe might have said it best (or at least the funniest) when they said: "O'Neil's literate lyrics feature the sort of off-kilter insights Emily Dickinson might make if alive today. After listening to commercial radio, hearing O'Neil sing is like reading Sylvia Path's brutally honest poetry in the wake of watching "American Idol”. In 2002, Marykate recorded and released her self-titled debut album, financing the project with 'pre-approved' credit cards. The record caught on among pop fans, and reached the top 10 of the CMJ charts. The record was released in Japan, Australia, and throughout Europe. Three songs from 'Marykate O'Neil' were covered by Japanese film and television star Tomoyo Harada. Soon after, the Nettwerk music group picked up "Marykate O'Neil" and re-released the album, broadening O'Neil's exposure. In 2006, O'Neil released "1-800-Bankrupt" which was hailed by Filter magazine as "pure magic" and Venus as "witty, angsty goodness." Also in 2006, O'Neil's song "Mundane Dream" was featured in the Sundance award-winning film "Stephanie Daley" starring Tilda Swinton, Amber Tamblyn, and Timothy Hutton. Performing Songwriter declared, "1-800-damn right! - the record sparkles with classic touches and Marykate's winning vocals are full of tenderness and humor throughout. To paraphrase XTC's Andy Partridge: 'It's really super, Supergirl’." In 2008, O'Neil released 'mkULTRA’ which made critics 'best of lists’ and World Cafe live saying: 'O'Neil is a mix of sugar and spice and sometimes everything not so nice'. The Weekly Dig said: "O'Neil has the unflappable ability to intertwine the sweet and sour like an expert bartender.” In 2009, Marykate released "Underground" which — not so subtly announced her (semi) exit from music and which All Music Guide said: "Underground suggests that O'Neil has indeed arrived.”
Most recently, O'Neil has focused on painting. While known for her songwriting, O'Neil has been honing her painting skills since she could stand. Her paintings are like visual manifestations of her songs -- both reflect her pop-sensibility, irony, humor and explore slices of daily life. O'Neil's art, in each media, is made up of primary colors and chords; is at once catchy and complex; and ready for the 'repeat' button. O'Neil's art is only available direct and is even being collected by 'some Hollywood fancy' pants.
