Final answer:
Artists like Santana, Los Lobos, Bob Dylan, and Leonard Cohen demonstrate the enduring nature of musicians who remain active with ongoing tours and cultural contributions well past their initial decades in the industry.
Step-by-step explanation:
The endurance of Santana and Los Lobos in the music industry since the early 70s is part of a broader pattern where musicians like Bob Dylan and Leonard Cohen have continued to remain active over the years, despite the passage of time. Both artists born in the first half of the 20th century have consistently contributed to the arts, with Bob Dylan being born in 1941, while Leonard Cohen was born earlier in 1934. Not only have they been actively producing music and poetry, but they are also still touring, showcasing their talents across the US and the world. Their longevity and enduring appeal to audiences highlight the timeless nature of their work and influence on contemporary music and culture.
