D-Side

D-Side were an Irish boy band established in 2001 by Irish twin doctors Rory and Eoghan Mac Sweeney and signed by Clive Black at Edel Records. The group got a recording contract in Japan with Avex. They enjoyed success in Japan, the United Kingdom, and Europe, winning 'Best New Band Award' at the Smash Hits Tour in 2002 and scoring 3 UK Top Tens.

The group was made up of five members, Derek Ryan (who performed under the alias Ryan O'Riain), Derek Moran, Damien "Dane" Guiden, Shane Creevey and Damien Bowe. The band released their first single "Stronger Together" in Ireland only, which reached No. 5 on the Irish charts. The group then released "Speechless", achieving three top 10 singles in the UK/Ireland and some around Europe. They supported Blue, Westlife and many other groups on tour during 2001 and 2002, before headlining their own live shows, as well as being involved in many charity events such as Soccer Magic, Soccer 6, Children in Need and ChildLine. In 2006, D-Side took part in the international contest "New Wave" in Urmala. They released three albums in Japan, and a greatest hits compilation through the Japanese record label Avex. After their split, Moran went on to present Milkshake! on Channel 5.
