Letting Go is the EP of Lo-Pro, initially available only during concerts in July and August during the "Stimulate This" Tour with Staind, Shinedown, Chevelle and Halestorm.

Lo-Pro's starting work on new material dates back to 2005, shortly after they were dropped from the Geffen Record label.

In summer 2005, they showed their first example of this new material when they streamed a copy of a new song, "Ingenious", from their Myspace, which, in the end, was not put on the EP.

Additionally, in early 2008, a full concert from 2007 was made available for streaming, which included live acoustic renditions of "Hang On", "Today", and "Letting Go".

Singer Pete Murray later claimed this was due to its inclusion on Lo-Pro's upcoming June 8, 2010 release The Beautiful Sounds of Revenge although it was later revealed that all songs except for "Today" were indeed put on it.

It refers not only the "letting go" of a personal relationship, but also to the traditional ways of releasing material in the music industry.

It’s a very exciting time to be a musician if you can just let go of how things used to be.” [4] While Lo-Pro certainly did not drastically change their sound, differences between their self-titled album and the EP are noticeable.

Additionally, the album is somewhat softer than their original effort, which is understandable considering several of the song were consistently performed acoustic.

“We’ve always been proud of the result but when you spend that much money right from the beginning, you feel like you’re trying to outrun this dark cloud all the time.

While the EP version retains the same song structure, it is fully electric and features fast paced guitar, bass and drum parts, with and extended outro.
