比利·吉本斯长期过去了ZZ顶部乐队成员达斯蒂·希尔（Dusty Hill）曾在2021年担任贝斯手，于2021年去世。
希尔在72岁的睡眠中去世，乐队继续与30年的吉他技术吉他技术埃尔伍德·弗朗西斯（Elwood Francis）继续前进，占据了他每个希尔（Hill）自己的愿望的位置。
在接受采访经典岩石，吉本斯回忆起希尔逝世的记忆，并说：“这是非常意外的。尽管达斯蒂（Dusty）对此进行了回合，但他似乎每次都反弹。实际上，当我们为巡回演出做准备时，我们进行了七天计划的排练，一切都在前面。除非我们出现第一次表演，否则Dusty并没有真正失去。我们度过了整个晚上，但我可以说他不是百分百。”
He continued, “And finally he said: ‘I’d like to take a moment and go see the physician and see if we can iron out what’s got me on the ropes.’ He returned to Texas and made an appointment to see the doc. And it was that night he went to sleep and it was… lights out. It was just… it was totally unexpected.”
当被问及乐队在希尔死后是否考虑过退休时，吉本斯说：“好吧，这是一个意外的现实，不仅落在了我的膝盖上，而且还使我能够与比尔德先生认真对待。我们两个人都同意，为了荣幸乐队的遗产，我们觉得试图拿起棍棒和继续前进，而不是只扔毛巾，这将是更合适的。”
He concluded by adding that the band are having just as much fun on stage as they ever have, noting that the addition of Francis to their outfit had a positive impact on keeping them powering on: “It’s quite a trip having Elwood step in to help keep the ball rolling. He’s adding a great bit of enthusiasm. When I see [drummer] Frank Beard smiling for the first time in thirty years, I know something good’s happening.”
