In 1994, the band signed a $35 million deal with RCA Records, releasing the million-selling "Antenna". Subsequent RCA albums, "Rhythmeen" (1996) and 1999's "XXX" (the second album to feature live tracks) sold well, but did not reach the levels enjoyed previously. In 2003, ZZ Top released a final RCA album, "Mescalero", an album thick with harsh Gibbons guitar and featuring a hidden track—a cover version of "As Time Goes By." RCA impresario Clive Davis wanted to do a collaboration record (in the mode of Carlos Santana's successful "Supernatural") for this album. In an interview in "Goldmine" magazine, Davis stated that artists Pink, Dave Matthews, and Wilco were among the artists slated for the project. ZZ Top performed "Tush" and "Legs" as part of the Super Bowl XXXI halftime show in 1997.
