Following in the footsteps of 
Justin Bieber and 
Soulja Boy, Croatian cellists Luka Sulic and Stjepan Hauser, aka 
2Cellos, were discovered through YouTube, after six million people viewed their classical cover version of 
Michael Jackson's "Smooth Criminal." Now with a major-label deal under their belt, the classically trained musicians face the tough prospect of translating what could be seen a one-trick pony novelty into a full-length album. It's a task made even more difficult considering that, unlike violinist 
David Garrett's forays into classical rock, which add layers of orchestral production on top of his virtuoso skills, the two 24-year-olds' self-titled debut doesn't feature any other instruments. Luckily, the pair's masterful talents, which seem to produce sounds from a cello that otherwise wouldn't seem possible, more than make up for the lack of background support. Indeed, other than the deliberately sparse reworkings of 
Johnny Cash's rendition of "Hurt" and second Jackson interpretation "Human Nature," its 12 tracks very rarely feel as stripped-back as one might expect, as the duo replicates the twanging guitar hook from 
Dick Dale's Pulp Fiction theme "Misirlou," the crunching riffs of 
Nirvana's grunge classic "Smells Like Teen Spirit," and the lilting piano chords of 
Muse's "The Resistance," using a combination of plucking, bowing, and frantic strumming. While the bombastic treatments of "Smooth Criminal" and 
Guns N' Roses' "Welcome to the Jungle" have received all the attention, the whole concept is just as effective on the slower numbers, as they turn 
Sting's flamenco-tinged "Fragile" into a mournful Gypsy folk ballad and transform 
U2's "With Or Without You" into a poignant instrumental suitable for a soundtrack to a 
Jane Austen adaptation. The ambitious project only really falters on the one track, which on paper seems best suited to their craft, with their adaptation of "Viva la Vida" sounding surprisingly flat when compared to 
Coldplay's already string-soaked original. But 
2Cellos is far from the classical karaoke affair one might have anticipated, as Sulic and Hauser have created an inventive first offering, with unique and innovative arrangements, that deserves to transcend their YouTube beginnings.
