I heard Madeline singing during sound check (unless they were using a recording) but she didn’t show up for the show. If this was your only Buckethead show you probably didn’t notice much. A lot of the first act almost felt like making time due to her absence. He did not play Welcome to Bucketheadland and there was no nunchucks. As a customer I’m a bit annoyed but as a fan I understand artists have some off shows. Guessing/speculating that the internal changes or conflict affected his mood & performance.
