For Rather Be Giraffes, a cappella is about more than just singing without instrumental accompaniment. It's also about having a good time, loving the music and seeing how many different unusual sounds its members can produce with their vocal chords.The group, now in its second year, reveled in these unique elements last Friday during their spring performance titled "Something for Everyone!" With remarkable poise, they stayed on key throughout the show, guided by nothing more than the simple humming of a pitch pipe. Their harmonies filled the vacuum left by an absence of instrumentation, even emulating electric guitars and drums. With an eclectic repertoire, Rather Be Giraffes delighted the audience.

They were joined by Interstate 8, a female a cappella ensemble from Worcester Polytechnic Institute. Interstate 8's performance, while as strong as Rather Be Giraffe's, concentrated on older themes, including the traditional melody "Swing Low, Sweet Chariot" and Simon and Garfunkel's "Scarborough Fair." Adding subtle twists to each song, they redefined the tunes, making them their own. Perhaps their only mistake was during their finale, the Chordette's classic doo-wop hit "Mr. Sandman," where they attempted a complicated harmonic sequence but broke into laughter as it fell apart.

With a second finale, the Spice Girls' "Wannabe," and some hilarious body language, their only faux pas was all but forgotten.

The evening's funniest moment, however, came when the female members of Rather Be Giraffes left the stage to their male counterparts, who then performed a hysterically exaggerated rendition of "Poor Unfortunate Souls," from Disney's The Little Mermaid. The song seemed to best combine the group's vocal talents and comedic flourishes-the group refused to limit itself on stage, as long as its antics provided a good time for both the performers and audience members.

Throughout the evening, Rather Be Giraffes revealed their zest for life, music and each other. The show's most poignant moment came during a farewell to seniors Rachel Rausch and Lauren Kaplan. Rausch, a founding member of the group, teared up as the rest of her ensemble presented her with a farewell gift-a clock fashioned in the shape of a guitar. As she sang a solo during the show's finale, Tom Cochrane's "Life is a Highway," the audience couldn't help but clap along.

And although Rather Be Giraffes certainly offered impressive harmonies and arrangements, they also benefitted from their chemistry and playful interactions. For the audience, this carefree approach to a cappella made "Something for Everyone!" much more enjoyable.
