[2] One of his earliest performance plays was Cockroaches Have No Friends, which led to him meeting Patssi Valdez, Harry Gamboa Jr., Willie Herrón and Sylvia Delgado, with the first three of them becoming members of Asco later on.

[11] Gronk often clashed with founder of East LA's Self Help Graphics, Sister Karen Boccalero, who he called "the smoking nun.

"[12] Gronk has not always sought to bring his art to just those who regularly visit galleries: he has circulated fliers about his work at "bus stops, seeking workers, students and the people of the streets.

"[10] Gronk uses his "lowbrow" style to confront the viewer and ask them to rethink "visual paradigms," using humor and irony to make his statements.

"[14] After 1984, Gronk began a series of paintings that included one of his recurring figures, La Tormenta who functions like a guide through his art.

More recently his murals have been intentionally painted as temporary art works (i.e., Fisher Gallery, University of Southern California) to be whitewashed later.

Comfortable with the moniker "Chicano artist", Gronk's intense devotion to craft and multi-disciplinary pursuits are informed by a wide knowledge from a myriad of global and historic sources.

In 1996, Gronk won a Los Angeles Dramalogue Award for Set design of the Theatrical play of "La Chunga".

He has collaborated with composer Joseph Julian Gonzalez on “Tormenta Cantada,” a visual/musical piece performed in 1995, and with Kronos Quartet at University of California, Los Angeles.

His characteristic black and white compartments appear to have been invaded and reworked by multiple hands, resulting in a densely interwoven palimpsest whose imagery and style reflect diverse sources, from Brancusi sculptures to graffiti-inflected Neo-expressionist painters.

"[25] The painting was created live during a 45 minute performance of a string quartet with a soprano (known as Tormenta), while Gronk worked an amplified paintbrush he treated as a conductor’s baton.
