T.I. vs Katy Perry – Dead and Cold

After using Traktor for about nine months, I’ve decided to record and release some mixes that I use.  My first mix is a mashup of the instrumentals from “Dead and Gone” by T.I. and the vocals “Hot N Cold” by Katy Perry.

Although I could make this in a cleaner way using different software, I decided to create this in Traktor 3 because it simulates a live performance environment.

HIST179 Final Paper: The 1811-1812 New Madrid Earthquakes

This was my final paper for HIST1790: North American Environmental History.  I decided to examine the historical accounts of the infamous New Madrid Earthquakes in Missouri in 1811-1812, largely because it complemented my interest in geology.

Convulsions of the Earth: The 1811-1812 New Madrid Earthquakes

Eliza Bryan awoke to the sound of thunder.  As she sat up, her house began to shake violently, knocking the thirty-one year old from her bed and toppling furniture as she crawled out of her room.  Clambering outside into the pitch blackness, distant booms from deep within the earth, reminiscent of heavy artillery, drowned out the cacophonous din of screaming neighbors, squawking birds, braying horses and mooing livestock.  Still unable to stand amidst the overwhelming shaking, Eliza heard nearby trees snap like twigs and the usually calm river roar angrily while a sulphurous vapor invaded her nostrils.  To the four hundred residents of New Madrid, Missouri, in the morning hours of December 16th, 1811, God’s wrath had come.

Posters: Lu’au and ¡Exótica!

This spring I designed two posters for on-campus events at Brown. Though I’m still figuring things out as I go in Photoshop and InDesign, they both came out quite nicely.


Chris asked me if I had any ideas for a cool poster to promote the Lu’au he was planning with the Hawaii Club. While brainstorming ideas, I thought of how much better the weather in Hawaii was compared to Rhode Island in February. That gave me the idea to create a trompe-l’œil window with a view of a Hawaiian beach, teasing the viewers’ plight while the slogan (shamelessly borrowed from Southwest Airlines) “Wanna get away?” encourages them to come. I found a suitable background photo, some good hi-quality wood textures for the window, and set to work. The final product was composed in Photoshop as a 300dpi 11″x17″ poster, set in Gotham and Commando.

Lu'au - 11"x17"


Matt and Roxy had asked me to DJ the Latino American Students Organization’s party in April. While planning for the event, I volunteered to draft a promo poster to replace the one Matt threw together in Microsoft Word. I used his layout, but used poster-quality images and textures that would be suitable for 11×17 printing. I compsoed the end result in InDesign and set the text in House Gothic 23 Bold Condensed 4.
