My source for almost all things science and music (and, often, pop culture), David Bruggeman announced this in a May 29, 2014 post on his Pasco Phronesis blog (Note: A link has been removed),

Tom [McFadden] would like your help, because he wants to remake the video with contributions from the ‘crowd.’  Between now and June 30 [2014], you can submit a visual for a minimum of one line of the song.

I’ll describe more about McFadden’s work in a moment but first, here’s the video of his ‘Older’ science rap,

Here’s a little more information about this latest McFadden project, from a May 27, 2014 post on his Science with Tom [McFadden] blog,

Introducing “Older”, a parody of Drake’s “Over”, about science as a process rather than as a body of facts.

If you are a science student of any age, a teacher, a scientist, or a science lover, I want you to submit your visuals for some part of this video. (And if you’re a science teacher, this is a fun end of the year activity for your students).

Please share the song/competition with anyone who may be interested, and tweet about it using #ScienceFolder.

The contest deadline is June 30, 2014. The Grand Prize is a performance of a full science rap show by Tom McFadden. I’m unclear as to whether or not he will travel outside the US, regardless, it looks like a fun project. From McFadden’s May 27, 2014 post,

VISUALS: You have lots of creative freedom here. Your visuals can be drawings, animations, stop-motion, shots of you rapping with props, or anything you can dream up. If you’re short on time, you can even just submit a photo of you with your science folder or lab notebook.

LENGTH OF SUBMISSION: If you want to be considered for the grand prize, you need to submit at least one line of the song (for example, you could choose “Teacher talking. Tympanic membrane swayin’” and come up with a visual for that line). You are welcome to submit visuals for multiple lines, for a full verse, a chorus, or for the whole song. If you are working as a class, you can have different students in charge of different lines.

There’ are additional details in the post.

I have more information about McFadden in a March 28, 2013 posting in the context of his Brahe’s Battles Kickstarter project,

I can’t resist the science rap stories David Bruggeman has been highlighting on his Pascro Phronesis blog. In his Mar. 26, 2013 posting, David provides some scoop about Tom McFadden’s Kickstarter project, Battle Rap Histories of Epic Science (Brahe’s Battles),

After Fulbright work in New Zealand and similar efforts in other countries, McFadden is back in the San Francisco area helping middle school students develop raps for science debates.  The project is called “Battle Rap Histories of Epic Science” (BRAHE’S Battles) and if fully funded, it would support video production for battle raps on various scientific debates in five schools.

This was a successful Kickstarter project as noted in my Aug. 19, 2013 post,

Now on to Tom McFadden and his successful crowdfunding campaign Battle Rap Histories of Epic Science (Brahe’s Battles); which was featured  in my Mar. 28, 2013 posting. Now, David Bruggeman provides an update in his Aug. 16, 2013 posting on the Pasco Phronesis blog,

Tom McFadden’s Brahe’s B.A.T.T.L.E.S. project has dropped two nuggets of video goodness of late, one of which is racing through the interwebs.  A conceptual cousin of the New York City-based Science Genius project, McFadden’s project centers around scientific matters of debate, if not controversy. First one out of the chute involves the matter of Rosalind Franklin and her under-credited role in developing the model of DNA.

I really meant it when I said David Bruggeman is my source.

Good luck to all the contest entrants!
