The band is hard at work rehearsing in it's new incarnation in hopes of returning to the road as early as March. 

Below is a press release from Great White's management.

Days before Great White was to embark on the European tour, lead guitarist Mark Kendall informed us that he was leaving the band. Great White immediately set out to find a replacement for the European tour. The Band recruited a lead guitar player who was familiar with the bands music, and 
invited him to join them on the tour in Europe. Due to the short amount of time available and scheduling, we had no time to set-up proper rehearsals. This would later prove to be quite costly.

Great White performed their first show in Madrid and it was apparent that the 
quality of performance was lacking, which resulted in a very mediocre show. The audience, fans and the band were unimpressed and disappointed by the 
overall lack of impact.

Great White immediately went into rehearsal in order to try and salvage and 
recapture its usual high performance level. However, the problem required much more attention, and due to the tight touring schedule, we were not able to adequately address the situation. The band feels in all good conscience that rather than presenting a substandard and disappointing show to its fans and public alike, Great White has no alternative but to cancel this much anticipated and important tour. This was clearly a very difficult decision for the band to make.

We apologize for any inconvenience and thank you for your patience and understanding of this very unfortunate incident. Great White has always been 
proud of and will always be indebted to its loyal and dedicated fans. Great White will be back, so stay tuned for an announcement of new tour dates in 
the very near future.
