He updated the Myriad series with blown-glass and new satin copper finishes, chosen to compliment the Negroni Sbagliato cocktail, which translates as "wrong Negroni".
This references when, in the 1960s, bartender Mirko Stocchetto mistakenly replaced the classic drink's gin with sparkling Brut wine, but decided the result was just as palatable.
The libation is now enjoyed by hundreds, who flock to the bar and spill out onto the surrounding streets each night during the design week.
"Bar Basso is the unanimous meeting grounds par excellence where Milanese locals and the Salone del Mobile design community mingle after-hours, revelling in the unpretentious institution's electric atmosphere that remains unchanged since the 1960s," said a statement on behalf of Scott.
Scott's light fixtures are displayed in the windows facing the street, glowing lurid orange like the Campari-based Negroni.
Others installed inside include versions of his alabaster glass and copper Welles lighting.
The Myriad series also comes in several other frame finishes, including Blackened Steel, Satin Brass, Satin Copper, Satin Nickel. The lamps are available as individual or double pendants, and tall or long chandeliers.
Bar Basso is located at Via Plinio 39. It hosted a party that Dezeen threw with British designer Lee Broom in 2016, when he parked his mobile exhibition space outside.
Another Dezeen party took place at Bar Basso in 2010. At the time, Maurizio Stocchetto told the story of how the bar had become a design-world institution during the annual furniture fair, in an interview we filmed on-site.
