Final answer:
David Gilmour of Pink Floyd is the guitarist known for his mature style and the iconic solo in the song 'Time'. His musical evolution is somewhat akin to the shifts in visual art styles shown by artists like David Hockney and Pablo Picasso, who also moved towards more imaginative and less traditional representations in their respective media.
Step-by-step explanation:
The guitarist referred to in the question is David Gilmour of Pink Floyd. His work, especially the guitar solo on the song Time from the album The Dark Side of the Moon, is widely celebrated for its emotional depth and technical proficiency. Gilmour's style has often been described as mature and nuanced, with a capacity to convey complex emotions through his instrument.
While David Gilmour's artistry in music is unmistakable, there are also artists in the visual arts who have shown similar maturity in their styles. David Hockney, for instance, began changing his perception of geometric imagery after being influenced by Wallace Stevens's poem The Man with the Blue Guitar. In Hockney's Self-Portrait with Blue Guitar, elements are tilted at an angle, departing from his previous style -- this can be paralleled with Gilmour's evolution in music.
We also have Pablo Picasso's Guitar (1912-14), a sculpture that showcases an innovative approach to art with its construction from sheet metal and wire, reflecting Picasso's exploration of form and abstraction. Picasso, much like Gilmour, broke away from traditional methods to create something distinct and new for the time.
