Once capped by England U-20s and also in the national youth sides, the Birmingham-born midfielder has had a turbulent 2003-04 season.
Murray signed for Harriers on an 18-month contract in January 2004 following a brief loan spell of three games earlier in the season.
But his temporary move was cut short when the attacking player checked into a clinic with a drinking problem.
When Murray recovered, he was released by Derby, who he had been with since the age of 12, and played games at non-league Solihull, Burton in the Conference and then Notts County in Division Two.
It has been a downward spiral for the energetic and tenacious player with an eye for goal after 32 games in the Premiership for Derby, many while still a teenager.
Murray also enjoyed a great loan spell at Mansfield when they were promoted from Division Three, scoring seven goals, and also trained with England U-21s.
Harriers beat off competition from various other clubs to clinch the signing of a player who is bidding to rebuild his career.
League appearances/goals: Derby (98/99) 4, (99/2000) 8, (2000/01) 14, (01/02) 6, Mansfield (loan) 13/7, Derby (02/03) 24.
