As 1Xtra gears up to celebrate two decades on air, we thought it timely to look back at the last time they celebrated a significant milestone. Back in 2012, when it was just 10 years they were celebrating, they called on two Cleo Sol and Angel to help them look back on some of the R&B hits that came out since the station went live.

Both singers are now rightly held up as veterans whose influence stretches right across music today (and let's be honest, Cleo Sol's last two albums are two of the finest ever released in UK R&B), but at the time they were the young upstarts with a prodigious talent ready to show the world, making this line-up a prescient one, to say the least.

Here they are, joined by a live band, running through Rihanna's "We Found Love", Mario Winans' "I Don't Wanna Know", Nelly & Kelly's "Dilemma", Ne-Yo's "So Sick", Beyonce's "Crazy In Love" and "One Thing", Wretch 32's "Don't Go", and rounding off with two of their own early hits: Cleo Sol's "Never The Right Time", Angel's "Wonderful"
