Like many people who used the enforced quiet time of a pandemic to re-make themselves, singer and songwriter Jack Eppington used the time to re-make one of his songs. He is now releasing the result: “Chrysalis Time,” a quirky, psychedelic, indie-rock song about personal renewal that he wrote in 2016. The track itself is new, and an improvement over the original production. He calls it “a weird song for weird times.”
