Question: What music video ,which made the director a two-time Grammy Award winner, amassed over 740 million views on YouTube?
Context: "Crystallize" is a song by American violinist Lindsey Stirling from her self-titled studio album, "Lindsey Stirling".  The song was released as a music video on YouTube on February 23, 2012.  The video proved to be a success, with more than 42 million views at the end of the year, and was the eighth-most watched video of 2012.  The song became Lindsey Stirling's album's lead single due to its success.  The song appeared on three "Billboard" charts and, according to Nielsen SoundScan, by April 2013 it had reached 234,000 digital sales.  On February 4, 2014, almost two years after the release of the video, "Crystallize" earned Stirling's first RIAA certified gold record by selling 500,000 copies in the United States.  At the end of 2013, on the year-end chart, "Crystallize" finished first in the chart of Classical Digital Songs.  On July 27, 2014, the official music video reached 100 million views, being Stirling's first YouTube video in doing so. The musical rock band OK Go has earned considerable fame for their creative but often low-budget music videos, most of which have been promoted through Internet video sharing sites like YouTube.  Many of these have become viral videos; the 2006 video for "Here It Goes Again", in which the band performed a complex routine with the aid of motorized treadmills, has received over 50 million views four years later.  Their video for Needing/Getting, released February 5, 2012 in partnership with Chevrolet, debuted during Super Bowl XLVI and has over 32 million views on YouTube.  Samuel Bayer, who produced many music videos in the 1990s, asserted that OK Go's promotion of music videos on the Internet was akin to Nirvana's ushering in the grunge movement.  Many of the videos also use long or single-shot takes, which "Salon"' s Matt Zoller Seitz says "restore[s] a sense of wonder to the musical number by letting the performers' humanity shine through and allowing them to do their thing with a minimum of filmmaking interference".  The success of OK Go's music first won the band the 14th Annual Webby Special Achievement Award for Film and Video Artist of the Year.  The video for "This Too Shall Pass" was named both "Video of the Year" and "Best Rock Video" at the 3rd annual UK Music Video Awards. "This Too Shall Pass" won the LA Film Fest's Audience Award for Best Music Video, UK MVA Awards – Music Video of the Year Winner 2010, among others.
