Odludek: Odludek is the debut solo album by Jimi Goodwin, released on Heavenly Recordings on 24 March 2014.  The album follows a few years after his band, Doves, announced they were taking an "indefinite hiatus."  The word "odludek" is a Polish word, meaning "pilgrim" or "loner."  Goodwin wrote and played almost everything on "Odludek" himself, with only a handful of guest musicians, including Elbow frontman Guy Garvey and former Dungen member Fredrik Bjorling, and the album was recorded and co-produced with Dan Austin at a studio in the Forest of Dean across 18 months.  Goodwin said, "Initially I wanted to have loads of guests on it.  Maybe I wasn't trusting my own instincts because I'd collaborated in a band for such a long time, but that idea soon went out the window.  Very quickly I decided I wanted to get my Prince head on and play everything.  I became very protective of it.  There was no-one steering me.  I made it myself and paid for it myself, and that was very free and liberating."
