Rizzle Kicks has been announced as the latest act to perform live in HD on the ‘BT Infinity Presents’ interactive YouTube channel.
The Brighton hip hop duo - whose debut album Stereo Typical was released last October - will play their biggest hits in front of an intimate audience of competition winners.
The gig will take place at 8pm on January 15th 2013 at the top of the BT Tower in London.
Fans who are not able to win tickets for the BT Infinity show will be able to stream the performance using their broadband connection.
They will also have the opportunity to get involved with the gig as it happens using a variety of social media tools.
David James, Marketing Director at BT Retail, said he was "delighted" to announce Rizzle Kicks as the third performance in the Live from the 34th Floor series.
"The boys are sure to deliver a fantastic performance, full of their usual energy," he stated.
On Monday December 10th, N-Dubz singer and X Factor judge Tulisa performed the second ‘BT Infinity Presents’ gig.
She followed in the footsteps of Conor Maynard, who got the series underway on November 20th.
Mr James noted that over a million people have got involved in the gigs online so far, by watching, tweeting and voting.
He said this has truly showcased the potential of super-fast fibre-optic broadband "to bring exciting, fully interactive and high definition online events into people’s homes".
BT is investing £2.5 billion upgrading its network infrastructure around the UK, in a bid to offer fibre broadband to two-thirds of all homes and businesses by 2015.
