A 'Don't Speak' speakeasy's just one of the attractions surrounding No Doubt's Sphere Las Vegas shows

The No Doubt Experience, a pop-up developed by the band's members, features a display of over 500 original artifacts from the band's archives. It includes stage outfits, instruments, flyers, the original No Doubt logo created by Gwen Stefani's brother and former bandmate Eric Stefani in 1987, and the rings that spelled out "Rock Steady" on the back cover of the band's 2001 album of the same name.
