'When It's Evening') is the debut single by the Dutch musical duo Suzan & Freek.

The duo rose to fame by posting covers of pop songs on Facebook.

[1] "Als het avond is" was the first original song that Suzan & Freek wrote.

[3] The song was written in an afternoon, and a demo was sent to Sony Music, who agreed to release it as a single.

[4] The success of "Als het avond is" allowed the duo to quit their jobs and focus on music full time – Suzan Stortelder as an interior designer, and Freek Rikkerink as a record label employee.

[9] It reached number one in March 2019 after 17 weeks on the chart, breaking a 48-year-old record previously held by Les Poppys' "Non, non, rien n'a changé" (14 weeks) for the longest climb to number one in chart history.
