The dim glow of holiday lights revealed the silhouettes of the band Shark Week as the musicians ran through a final sound-check in the SIS Founders‰’ Room to send the evening on its merry way. Without much further hesitation, the band filled the makeshift venue with their signature throwback rock-and-roll sound. After a handful of original tunes, students in attendance already started swinging their hips.

One brief intermission later, DeMarco and his band armed themselves with their instruments and took their stance in front of the floral-patterned tapestries and Ron Paul apparel that adorned the walls. They began with a few of their more popular songs including “Ode to Viceroy‰” and “My Kind of Woman,‰” which was answered with jumping and moshing on the audience‰’s side of the stage. The band‰’s audio behaved much more punk-like than on its recordings in the way the sound embraced the atmosphere in which it was contained.

In terms of the performance, Mac DeMarco evoked the vibe of an interactive jam-session; the concert ultimately shifted into a medley of cover songs which flowed from one musical reinvention to another. Mac relinquished the mic for a cover of Led Zeppelin‰’s “Stairway to Heaven‰” and before the crowd realized, they were deeply grooving to “Schism‰” by Tool with the band‰’s bassist gutturally barking the chorus. These covers often derailed into chaotic improvisation with the artists on their knees prying dissonant sounds out of their instruments.

After concert-closer “Still Together,‰” the crowd still was not quite ready to relent, and Mac‰’s pleas to party were repeatedly met with enthusiasm. The band portrayed itself nobly: as a solid crew looking to have fun. Surely, for those present, the SIS Founders‰’ Room will invoke the intensity of that night for some time to come.
