Her 2015 album, Be Brave, was produced by Toby Gad.[7] Temtchine wrote the title track in 2014 after she was released from intensive care. Amy Carlberg of Bust magazine wrote that the track was "twangy and energetic, and springboards off the bluegrass and banjo-laden sounds that have been ruling the pop charts".[8] Over 150,000 copies of the album were downloaded within the first 90 days of its release.[9]
In August 2020, Temtchine suffered a cardiac arrest, was in a coma, and spent 21 days on life support before receiving a double lung transplant. She required the continuous use of an oxygen tank that was connected to a nasal breathing tube, and in February 2021, Chloe (who sings with a paralyzed vocal cord) performed live for the first time since the transplant.[citation needed]
