Calvert toured as Redinho, playing at major venues and festivals worldwide including SXSW, Primavera, and Sónar. He also collaborated witt Rustie and rapper 100s. He released the single "Searching" on Numbers in 2013. Notable fans within the industry at the time included Hudson Mohawke. Calvert's full length album Redinho was released on Numbers in September 2014. Dazed called it "a debut album... ecstatically full of life and colour." The album included vocal contributions from Brendan Reilly, Vula, and Vanessa Haynes. During 2015 and 2016, Calvert became the member of Hudson Mohawke's live band for his Lantern album campaign. During a BBC Radio 1 Maida ValeLive Session, Calvert was also interviewed by radio DJ Annie Mac through a talkbox. In 2017, under his own name, Calvert released a beat tape titled Zanbor, accompanied by a film made by filmmaker and producer Abdullah Al-wali. In early 2018, Calvert released "Square One" featuring Kimbra. Calvert also produced "Sweet Relief" for Kimbra in 2016. In 2018, Calvert won international artist grants from the Arts Council and the PRS Foundation Momentum Fund, and was awarded the British Council's Musicians In Residence and worked in Fortaleza, Brazil. In March 2019, Calvert released "Snake Skin Boots" featuring LA rapper Blimes on Roya. This single, as well as another single Calvert released, "Mmm Mmm" a year before in March 2018, also on Roya, were both consecutively crowned Annie Mac's "Hottest Record In The World" on BBC Radio 1. In August 2019, Calvert released "Nova Special" on Roya Records. The single's video was shot in Athens, Greece. In October 2019, Calvert released "Sheriff" featuring South London singer Joel Culpepper. In March 2020, Riz Ahmed's album The Long Goodbye was released, an album produced entirely by Calvert. The Guardian wrote that "The Long Goodbye’s main currency is pointed blasts of sound, where rattling percussion and samples of traditional Indian and Pakistani instruments and singing, the latter frequently looped into insistent, hypnotic motifs, clash against bursts of harshly distorted electronics. On occasion, it slips into more commercial territory – Karma has a hint of tropical house about it, Deal With It has an impressively hooky pop melody – or something that sounds suspiciously like musical satire: Jay Sean’s appearance on Any Day repurposes Drake’s Auto-Tuned solipsism for socio-political ends. But its most thrilling moments are its harshest: the frantic Fast Lava, the scourging, stammering eruptions of Toba Tek Singh."
