More and more, the pastels and gold-leaf embellishments have given way to the contemporary, but unimaginative, tungsten hue

Richard Segovia’s house is as loud as the Latin rock music he teaches children to play in his basement studio. With colors ranging from jungle green and royal blue at the pavement to a red and yellow sunburst at the ridge, the otherwise modest Spanish-style home is essentially one enormous mural, a crowded portrait of long-gone musicians, Segovia’s family members, social activists, various psychedelia, and the odd jungle animal.

Segovia has lived in San Francisco’s Mission district since 1963, and he sees himself as a custodian of the neighborhood’s culture, specifically as the birthplace of Latin rock. (Carlos Santana, a family friend, grew up nearby.) But increasingly the 68-year old “Mayor of the Mission” finds himself face to face with a stark representation of all the color that has been bled out of the city over successive waves of tech-fueled gentrification.
