Patrick Brill OBE RA (born 1963), better known by his pseudonym Bob and Roberta Smith, is a British contemporary artist, writer, author, musician, art education advocate, and keynote speaker.

[8] Smith paints slogans in a brightly coloured lettering style on banners and discarded boards of wood and exhibits them in galleries of contemporary art across the world.

[2][13] Writing of a launch event in "glittering Notting Hill Gate" (i.e. in fashionable and central Kensington), Lynn Barber said of Smith: "It was a startlingly unsuitable subject for such a glossy audience, but he held them spellbound.

I see him as a sort of Ian Dury of the art world, someone who keeps on trucking, doing his own thing, making absolutely no concessions to fashion or marketability, but generally giving pleasure to everyone who comes across him.

[3] Brill is an associate professor at the School of Art, Architecture and Design at London Metropolitan University, teaching undergraduate and post-graduate students.

[3] Brill performs music, often with a group he co-founded, The Ken Ardley Playboys,[3] who had their first 45 released by Billy Childish on his label Hangman Records.

Brill hosts The Bob & Roberta Smith Radio Show called Make Your Own Damn Music on Resonance FM.

[3][17] Brill stood in the Surrey Heath constituency in the 2015 general election, under his working name, Bob and Roberta Smith.
