There are at least 4 acts under this name :

1)Retrospect is a Thai Post-Hardcore/Rock band which started off around 2003.

Their first EP called For Your Ears Only got released in the following summer through ScreamLab Records and immediately drawed attention to the young band. Not that much later they got signed by Genie Records, a GMM Grammy subsidiary and one of the leading Thai record Labels, and were able to put out their first full-length Unleashed in 2007. Their first DVD: The First Concert, showed the boys in their natural habitat and showed a lot of their talent by letting them do duets and featurings with other Genie stars as Da Endorphine and Tao from Sweet Mullet.

More recently, in July 2008, came the follow up to their debut: Rise and in December of the same year they released their second DVD/VCD of the new tour called Rise Now!

They end up in the Thai charts with their music-videos and singles and often stand out in-between the more Pop-orientated Thai culture. Retrospect took Thailand by storm and will not rest before the rest of the world has heard of them.
