Say what you will about Lady Gaga...the woman might just be the talent to define her era. While not a fan of the whole performance artist thing...go beyond the costumes, hair, make-up...definitely keep the attitude, and then you have the voice.
Even "back in the day" various artists like Kiss, Twisted Sister, David Bowie and Madonna, re-invented themselves to stand out from the crowd. Lady Gaga takes it to a new level. In this wasteland that is music today, I kind of wish her great stuff would have been heard without all the distraction.
Case in point. Listen to this clip of a live performance of "The Edge of Glory" on the Howard Stern show. The power of this vocal is just breathtaking. Drink it in.
