Sandbox is the second studio album developed by Widespread Panic Lead Guitarist Michael Houser.

Released posthumously in 2006, 'Sandbox' is a collection of Houser originals Recorded at John Keane's Athens, GA studio in August 2002, shortly before his death from pancreatic cancer.

[1] In contrast to Door Harp, the tracks are mostly full-band rockers, several of which had been played by Widespread Panic in the past.

[2] Also unlike Door Harp, the songs are all accompanied by Houser's low-key vocals.

A two-song bonus CD with outtakes was included with the original release in 2006.
