Over the next 12 years, Crazy Horse would steadily collaborate with Young, joining him for Sleeps with Angels (1994), Broken Arrow (1996), the live album Year of the Horse (1997), the shelved Toast (recorded 2001) and Greendale (2003). Sampedro was instructed to sit out the recording of Greendale, as Young felt the material called for only one guitar, and considered leaving the band; he ultimately joined the band on guitar and organ for the ensuing tour of 2003-2004. According to Jimmy McDonough, Crazy Horse had begun a sixth album of its own in the mid-1990s, but left the project unfinished when Young called upon the group to join him for some secret club dates in California (for which the quartet billed themselves as the Echoes), leading to the recording of Broken Arrow. Crazy Horse remained on hiatus for seven years following the Greendale tour. Although Sampedro was employed as a full-time assistant to Kevin Eubanks on The Tonight Show with Jay Leno from 1992 to 2010, the band continued to rehearse several times a year and more intermittently with Young during this period. Trick Horse—based on previously unreleased Crazy Horse recordings, possibly derived from older Sampedro-funded sessions where session musicians were hired to play the instrumental parts—was released on iTunes in 2009. According to Young in a 2011 interview with American Songwriter, "They have to be together before I can be together with them. They haven't been doing anything together, so they need to be able to do it. I don't have the time to support things. I have to go with things that are going to support me. But I think they can do it." Shortly thereafter, Neil Young and Crazy Horse convened to record two new albums, both of which were released in 2012. Americana was composed entirely of covers, mostly of American folk music revival songs and standards, while Psychedelic Pill featured original Neil Young songs written for the band. Neil Young and Crazy Horse embarked on the Alchemy Tour throughout 2012 and 2013 in support of both albums, traveling to the United States, Canada, Australia, New Zealand, and Europe. In 2013, Talbot, Molina, George Whitsell, and lead vocalist/guitarist Ryan James Holzer formed Wolves. They released their first recording, Wolves EP, on February 16, 2014. With the addition of background singers Dorene Carter and YaDonna West, Young and Crazy Horse toured Europe in the summer of 2014
