German power metallers GAMMA RAY have tapped Kasperi Heikkinen of AMBERIAN DAWN and the Finnish GAMMA RAY tribute band GUARDIANS OF MANKIND as the temporary replacement for guitarist/keyboardist Henjo Richter, who underwent surgery on Tuesday (March 16) for a "retinal detachment."Affected dates: March 19 - Lichtenfels, GER @ Stadthalle
March 20 - Prague, CZR @ KD Vltavska
March 22 - Langen, GER @ Stadthalle (rescheduled from March 18)
March 23 - Saarbrücken, GER @ Garage (rescheduled from March 16) Henjo is expected to rejoin his GAMMA RAY bandmates in time for the March 25 concert at KB in Malmö, Sweden. A retinal detachment is a disorder of the eye in which the retina peels away from its underlying layer of support tissue. Kasperi previously filled in for Henjo for a few shows in 2006.

"To The Metal", the new album from GAMMA RAY, was released in North America on March 16 via a new deal between DisManic Distribution and Knife Fight Media. GAMMA RAY — Kai Hansen (vocals/guitar), Dirk Schlächter (bass), Henjo Richter (guitar) and Daniel Zimmermann (drums) — recorded a total of twelve new songs last fall at its own studio in Hamburg. Ten of the tracks appear on the regular album release, while the remaining two cuts are available on various editions of the album. Italian web site SpazioRock.it conducted an interview with Kai Hansen before GAMMA RAY's February 16, 2010 concert in Milan, Italy. You can now watch the chat below.
