TRESOR referred to the album as his most personal project. Explaining his album:
Nostalgia is a sonic trip into my childhood; I basically went back into the music era I grew up in, listening to the music that shaped who I am from the likes of Hugh Masekela, Papa Wemba and Chico Twala. I just boxed all that music and interpreted in a way that allows me to show people what moulded me into the artist I’ve become as an adult.[4]
"Aphrodite" is the second song that was released from Nostlagia, after The Soil-assisted "Silale," which came out in early September. The song featured Afro pop band Beatenberg. TRESOR telling People Magazine about the song:
I am truly thrilled to share this collaboration with my Beatenberg brothers. The song was written and produced in Cape Town throughout summer last year. Matthew Field (of Beatenberg) and I wanted to create a musical piece that reflects the sounds that we both grew up listening to. We both love Greek mythology and history, so we wanted to play with idea of falling deeply in love with Aphrodite, an ancient Greek goddess associated with love, beauty, pleasure, and procreation. We had so much fun making this song and I think we created something truly magical. Excited to share it with the world.[7]
The eleventh song, "Sondela" featured South African singer Msaki. The song was nominated for record of the year at the 26th South African Music Awards[9] and was certified 5× Platinum by the Recording Industry of South Africa.[6] The music video was released on 13 April 2019 and was directed by Marty Bleazard under creative direction of Tresor's references to Beyoncé's iconic Vogue Magazine takeover in September 2018.[10] The music video reached 1 million views on YouTube three months after its release.[11]
