Helm charges Robertson with authoritarianism and greed, while Robertson suggests his increased efforts in guiding the group were largely because Danko, Helm, and Manuel were becoming more unreliable due to their heroin usage. Robertson insists he did his best to coax Manuel into writing more songs, only to see him descend into addiction. Despite mounting problems among the group members, the Band forged ahead with their next album, Cahoots (1971). Cahoots featured Bob Dylan's "When I Paint My Masterpiece", "4% Pantomime" (with Van Morrison), and "Life Is a Carnival", the last featuring a horn arrangement by Allen Toussaint. Toussaint's contribution was a critical addition to the Band's next project, and the group would later record two songs written by Toussaint: "Holy Cow" on Moondog Matinee and "You See Me" on Jubilation. In late December 1971, the Band recorded the live album Rock of Ages, which was released in the summer of 1972. On Rock of Ages, they were bolstered by the addition of a horn section, with arrangements written by Toussaint. Bob Dylan appeared on stage on New Year's Eve and performed four songs with the group, including a version of "When I Paint My Masterpiece". 1973–1975: Move to Shangri-La In 1973, the Band released the covers album Moondog Matinee. There was no tour in support of the album, which garnered mixed reviews. However on July 28, 1973, they played at the legendary Summer Jam at Watkins Glen, a massive concert that took place at the Grand Prix Raceway outside Watkins Glen, New York. The event, which was attended by over 600,000 music fans, also featured the Grateful Dead and the Allman Brothers Band. It was during this event that discussions began about a possible tour with Bob Dylan, who had moved to Malibu, California, along with Robertson. By late 1973, Danko, Helm, Hudson and Manuel had joined them, and the first order of business was backing Dylan on the album Planet Waves. The album was released concurrently with their joint 1974 tour, in which they played 40 shows in North America during January and February 1974. Later that year, the live album Before the Flood was released, which documents the tour. During this time, the Band brought in Planet Waves producer Rob Fraboni to help design a music studio for the group. By 1975, the studio—known as Shangri-La—was completed. That year, the Band recorded and released Northern Lights –
