This album contains two tributes to two other stellar guitarists.
One of those is "Jiboom," which pays homage to Stevie Ray Vaughan, while "Frank" remembers Frank Zappa.
Vai saw his career begin as a teenage stunt guitarist for Frank Zappa.
Later, Mike Keneally performed the same role in a band backing Zappa.
For this album, Keneally toured in Vai's band, but plays keyboards on the album.
It is an amazing exhibition of six-string talent.
