@Mr. Slash : to me, Myles has different ways of singing. In the Mayfield Four and ODR records, he had a certain subtlety that is totally missing in his recent ouputs. When he sings with Slash, he uses a "hard rock style" that I find very generic and unappealing. His groove and the way he pronounces words is just different. Unfortunately, he's been using that style more and more over the years.
That's why I'm anticipating his solo album like crazy. I have no more hope for any greatness on the forecoming AB and Slash records : I pretty much much know what to expect, and it's just gonna be decent/good like anything Mark-related since 2007. But Myles has said his solo album was similar to the MF4 albums, and to me, that's when his vocals were at their peak. I just want to hear that voice once again.
As to Elvis, well, if you can't hear he's bad at his job, good for you. I guess that allows you to enjoy the music despite its obvious sonical flaws.
