Wilson Vincent Mazarello (born Wilson Constantino Vicente Mazarelo; 19 July 1946), also known as Wilmix, is an Indian singer, writer, playwright, and politician known for his work in Konkani films, and tiatr productions.

Mazarello received his early education in Portuguese (Pimeiro - Gravo) at Velim before moving to Bombay to continue his studies in English. From an early age, Mazarello displayed a keen interest in singing. He would save his money to attend tiatr performances, a popular form of theatre in Goa. Although his parents also participated in local shows, they were determined for their son to receive a good education and pursue a successful career.

Despite their wishes, Mazarello continued to nurture his passion for tiatr by contributing through songwriting, but he did not actively pursue acting in these productions. After completing a bachelor's degree in science from Bombay University, he embarked on a career in Bombay. Mazarello furthered his education by studying Business Management & International Marketing, eventually rising through the ranks to become an export manager in a pharmaceutical company. This position afforded him the opportunity to travel extensively to various countries in Europe, Africa, and Asia for business purposes. During his time at St. Xavier's College, Mazarello served as the president of the Konkani Mandal for two years. One of his achievements during his tenure was the establishment of a library dedicated to Konkani literature at the college. Mazarello held great admiration for the Konkani actor A. R. Souza Ferrao, and it was during his family's relocation to Bombay that he had the chance to closely observe and appreciate the intricacies of the Konkani stage.

Mazarello is the owner of Rhythm House music shop in Margao, Mazarello has fostered connections with tiatrists such as M. Boyer, Chris Perry, Alfred Rose, and C. Alvares, commemorating their presence through life-size cut-outs displayed at his establishment. Marcus Mergulhao, from The Times of India, hails Mazarello as a distinctive and atypical tiatrist with a unique command over words.

Mazarello is known for his significant contribution to the preservation of Konkani tiatr by publishing a comprehensive book titled 100 Years of the Konkani Tiatro in 2000. This meticulously crafted 406-page volume serves as a definitive resource, chronicling the rich history of Goan tiatr. It contains printed versions of tiatr handbills dating back to the 1800s, complemented by photographs of renowned tiatrists, important historical dates, significant landmarks, and valuable information about the pioneers and contributors who have shaped tiatr culture. Mazarello's accomplishments extend beyond the literary realm. Alongside his wife Sharon Mazarello, he achieved international recognition by securing a place in The Guinness Book of World Records. Their feat involved participating in the longest non-stop singing marathon of choral groups, known as Konkani Nirontari, held at the prestigious Kala Angan in Mangalore. Their performance lasted an astounding 49 hours, surpassing a previous record held by a Brazilian group. The authenticity of their achievement was duly verified by Guinness officials.

Not only has Mazarello made contributions to the literary and performance aspects of tiatr, but he has also ventured into the realm of children's literature. He published a book of Konkani stories designed for young readers, evoking a sense of nostalgia akin to the tales passed down by grandparents. Additionally, as of 2013, Mazarello was engaged in writing his autobiography, a project that, if had completed within 2014, would have had mark a pioneering endeavor as the first tiatrist to chronicle his own life story. Mazarello's artistic prowess extends to the stage, where he has excelled as a performer. He is widely known as Wilmix, the founder of the popular Wilmix trio. During the 1980s, this trio played a pivotal role in reviving the trio-culture.

Mazarello and his wife Sharon have established themselves as highly sought-after duet performers in the Konkani music industry. Mazarello's journey as a performer began after completing his college education, when he developed a strong aspiration to showcase his singing abilities on stage. Recognizing his talent, Mazarello sought a platform to launch his career but encountered challenges due to his limited industry connections. During this time, Mazarello's primary contact was Fr Avertano Nazareth, a priest associated with Dabul church, who had connections with Frank Fernand, a Konkani music composer known for his work in movies such as Amchem Noxib and Nirmonn. Mazarello, due to professional obligations and personal commitments, was unable to actively participate in stage performances. Nonetheless, he maintained a keen interest in dramas and diligently followed the Konkani weeklies, which served as a platform for advertisements and news related to tiatr, a popular form of Goan musical theater. It was during this time that Mazarello encountered an advertisement for a musical show called Bekar Patrao, composed by Frank Fernand.

Intrigued by the opportunity, Mazarello sought out Rico Rod, the individual responsible for overseeing the artists and skits involved in the production. With the guidance of Fr. Avertano Nazareth, Mazarello, who was also studying solfeggio, was introduced to Aniceto Fernandes, the publisher of a prominent Konkani weekly. Through these connections, Mazarello managed to establish contact with Rico Rod, who agreed to include him in a trio performance, provided that Mazarello arranged his own singers. Despite the challenges involved, Mazarello persevered and successfully enlisted two of his friends as fellow vocalists. The trio's performance garnered resounding applause, prompting one influential musician to express the sentiment that the Konkani stage would benefit from the addition of more such talented individuals. The show itself was presented in seven different locations, further extending their reach.
