===Concert sound systems===
The [[Wall of Sound (Grateful Dead)|Wall of Sound]] was a large sound system designed specifically for the band.<ref>{{cite web|url=http://www.pechner.smugmug.com/gallery/2383161|title=Pechner Productions- powered by SmugMug|publisher=Pechner.smugmug.com|access-date=July 16, 2011|url-status=dead|archive-url=https://web.archive.org/web/20091125144654/http://www.pechner.smugmug.com/gallery/2383161|archive-date=November 25, 2009}}</ref><ref>{{cite web|url=http://www.alembic.com/family/history.html|title=Alembic History&nbsp;– Long Version|publisher=Alembic.com|date=August 22, 2001|access-date=July 16, 2011|url-status=live|archive-url=https://web.archive.org/web/20110712132709/http://alembic.com/family/history.html|archive-date=July 12, 2011}}</ref> The band was never satisfied with the house system anywhere they played. After the Monterey Pop Festival, the band's crew 'borrowed' some of the other performers' sound equipment and used it to host some free shows in San Francisco.<ref>{{cite web|url=http://lostlivedead.blogspot.com/2010/01/may-june-1967-grateful-dead-itinerary.html|title=May–June 1967 Grateful Dead Itinerary Overview|publisher=lostlivedead.blogspot.com|date=January 1, 2010|access-date=October 16, 2011|url-status=live|archive-url=https://web.archive.org/web/20110919184758/http://lostlivedead.blogspot.com/2010/01/may-june-1967-grateful-dead-itinerary.html|archive-date=September 19, 2011}}</ref> In their early days, soundman [[Owsley Stanley|Owsley "Bear" Stanley]] designed a [[public address]] (PA) and monitor system for them. Stanley was the Grateful Dead's soundman for many years; he was also one of the largest suppliers of [[Lysergic acid diethylamide|LSD]].<ref>McNally, Dennis, "A Long Strange Trip", New York 2002, pp. 118–19. {{ISBN|0-7679-1185-7}} and Brightman, Carol, "Sweet Chaos", New York 1998, pp. 100–04. {{ISBN|0-671-01117-0}}</ref> 

Stanley's sound systems were delicate and finicky, and frequently brought shows to a halt with technical breakdowns. After Stanley went to jail for manufacturing LSD in 1970, the group briefly used house PAs, but found them to be even less reliable than those built by their former soundman. On February 2, 1970, the group contacted [[Bob Heil]] to use his system.<ref name="performing">{{cite news|url=http://www.performing-musician.com/pm/dec08/articles/bobheil.htm?print=yes#top|title=The Night that Modern Live Sound Was Born: Bob Heil and the Grateful Dead|last=Daley|first=Dan|date=December 2008|publisher=Performing Musician|access-date=May 7, 2011|archive-date=October 5, 2011|archive-url=https://web.archive.org/web/20111005221916/http://www.performing-musician.com/pm/dec08/articles/bobheil.htm?print=yes#top|url-status=dead}}</ref> In 1971, the band purchased their first [[solid state (electronics)|solid-state]] sound system from [[Pacific High Recording|Alembic Studios]]. Because of this, [[Alembic Inc|Alembic]] would play an integral role in the research, development, and production of the Wall of Sound. The band also welcomed [[Dan Healy (soundman)|Dan Healy]] into the fold on a permanent basis that year. Healy would mix the Grateful Dead's live sound until 1993.

Following Jerry Garcia's death and the band's breakup in 1995, their current sound system was inherited by [[Dave Matthews Band]]. Dave Matthews Band debuted the sound system April 30, 1996, at the first show of their 1996 tour in Richmond, Virginia.
