Musicologist James Perone credited Bowie with having "brought sophistication to rock music", and critical reviews frequently acknowledged the intellectual depth of his work and influence. The Human League founder Martyn Ware remarked that he had lived his life "as though he were an art installation." The BBC's arts editor Will Gompertz likened Bowie to Pablo Picasso, writing that he was "an innovative, visionary, restless artist who synthesised complex avant garde concepts into beautifully coherent works that touched the hearts and minds of millions". U2 lead singer Bono commented, "I like Bowie when he’s evenly pulled in the direction of being a pop star and Picasso, where he's right down the middle. That’s usually my favorite, when the songwriting is disciplined but the recording is not. I love when he's pulled equally in the directions of art and populism."
