After that shocking revitalizaion that Arnel experienced a year or so ago, it's seems that he's become rather hit or miss these days. (After 3 weeks off, he did 2 back to back shows, where he seemed to sound excellent. Then, after 2 days off, he sounded a bit rough again!)
So, my big question is..."Why don't they just detune the songs again, rather than let him struggle on signature songs like Lights & Separate Ways?"
