The High as Hope Tour (Aug 5, 2018 – Sep 22, 2019) was the fourth concert tour by Florence and the Machine, in support of their fourth studio album, "High as Hope".. Billie Eilish opened at the Nashville and Charlotte shows in 2018 and at the Adelaid and Geelong shows in Australia in 2019
Grace opened at four concerts in June 2019, as a replacement for Nathaniel Rateliff and The Nightsweats, as Radcliff need treatment for a hearing issue.
As an opener, Grace did not get much press. Glide Magazine wrote: about the Orlando show "Grace VanderWaal opened the night with her unique brand of folk-pop [and] gave an energetic performance, singing and playing ukulele over pulsing pop beats."
