At age 15, Barlow became a student at the Fountain Valley School in Colorado Springs, Colorado. There he met Bob Weir, who later co-founded the Grateful Dead. Weir and Barlow maintained a close friendship through the years.

As a frequent visitor during college to Timothy Leary's facility in Millbrook, New York, Barlow was introduced to LSD; he later claimed to have consumed the substance over 1,000 times.[10] These transformative experiences led him to distance himself from Mormonism. He went on to facilitate the first meeting between the Grateful Dead and the Leary organization (who recognized each other as kindred souls in spite of their differing philosophical approaches) in June 1967.[15]

While on his way to California to reunite with the Grateful Dead in 1971, Barlow stopped at his family's ranch, not intending to stay. His father had suffered a debilitating stroke in 1966 before dying in 1972, resulting in a $700,000 business debt. Dismayed by the situation, Barlow changed his plans and began practicing animal husbandry under the auspices of the Bar Cross Land and Livestock Company in Cora, Wyoming, for almost two decades. To support the ranch, he continued to write and sell spec scripts.[10] In the meantime, Barlow was still able to play an active role in the Grateful Dead while recruiting many unconventional part-time ranch hands from the mainstream as well as the counterculture.[16] Prior to his death in 2018, John Byrne Cooke intended to produce a documentary film (provisionally titled The Bar Cross Ranch) that documented this era.[17]

Barlow became interested in collaborating with Weir at a Grateful Dead show at the Capitol Theatre in Port Chester, New York, in February 1971. Until then, Weir had mostly worked with resident Dead lyricist Robert Hunter. Hunter preferred that those who sang his songs stick to his "canonical" lyrics rather than improvising additions or rearranging words. A feud erupted backstage over a couplet in "Sugar Magnolia" from the band's most recent release (most likely "She can dance a Cajun rhythm/Jump like a Willys in four-wheel drive"), culminating in a disgruntled Hunter summoning Barlow and telling him "take [Weir]—he's yours".[18]

In late 1971, with a deal for a solo album in hand and only two songs completed, Weir and Barlow began to write together for the first time. They co-wrote songs such as "Cassidy", "Mexicali Blues" and "Black-Throated Wind", all three of which remained in the repertoires of the Grateful Dead and of Weir's varied solo projects.[19] Barlow subsequently collaborated with Grateful Dead keyboardist Brent Mydland, a partnership that culminated in four songs on 1989's Built to Last. He also wrote one song ("The Devil I Know") with Mydland's successor, Vince Welnick.[20]
