[4] Wolf Trap is a National Park in Virginia, where the band performed live on July 25.

In addition to the CD, a DVD was released featuring, in addition to the CD setlist, "People Gotta Love Again", "Spirit", "Nobody", "Neal's Fandango", "Takin' It to the Streets" and "Without You", interviews, a photo gallery and other bonus features.

The album was also released as a double LP vinyl set, same tracklist as the CD version.

The album revived a handful of tracks the Doobies had not released live versions of before from Tom Johnston's original stint with the band.

The album contains the final recordings of drummer and vocalist Keith Knudsen, who died shortly after its release.
