Although it's the first time I've listened to Fredo Viola, he's certainly not all new at the online music scene. According to his bio (link at the bottom of this story) he already had his first cyberspace success in 2004. In that year one of his early songs (The Sad Song) had been licensed for The Manchurian Candidate.
Apart from this song, the Fairtilizer player below also features the following songs: Red States, Red States Vaccaro Mix, The Turn (A Pagan Lament) and Our Lips Are Sealed (The Go-Go's cover). More songs are amongst others on his Fairtylizer account. The songs come from either the The Sad Song (February 2008) and Red States (December 2008) EP or the also in December 2009 published full album The Turn. Check Fredo Viola's news page for availability.
Fredo Viola was born in the UK but raised in the US. That's where he made his fabulous vocal music. On the contrary to what you might think, he doesn't have a choir a la The King's Singers behind him. He does all A Cappella singing by himself, which he is able to because of his boy choir experience.
He also has a beautiful designed website. According to Wikipedia, he's a multi media artist, so he most likely did the design himself. It's definitely worth a visit.
