2004

In October 2004, Dan Sullivan made the decision to leave the band to continue his education. Within a month of his departure, however, the band enlisted guitarist Aleksander Kmiec. Aleks soon became known as "Aleks with a K" due to the spelling of his name, and to differentiate between the band's singer and guitarist. Within weeks, the band began playing shows again. However, between Aleks' arrival and the release of their first EP, the band played infrequently.

2005

The band's success did not begin to grow significantly until February 2005, with release of their first EP entitled "The Modern World, A Battlefield". In support of the release, the group tirelessly played at local venues and continued to write as their fan base grew. Their second independent release, simply entitled "The Summer EP", became available (strangely enough) in the fall of 2005, and was proof that the band members were maturing musically as individuals and as a whole.

During the summer of 2005, Brandon became a temporary drummer of the band Vanna. This quickly became a full-time commitment, and the band was signed to Epitaph Records before the end of the year. Brandon and the rest of the band members made the decision to have him leave Therefore I Am and continue playing drums for Vanna. His last show with the band would be in the winter of 2006.

During the fall of 2005, the band members completed recording the song, "I Get Nervous in Cars,". This version of the song was posted online and would later be released on the Therefore I Am/Vanna Split 7-inch and the "You Are Connected" EP. The split 7-inch was first made available at the Robotica Records album release party on March 10, 2006.

2006

Brian Marquis, Shawn Marquis' (Vanna) brother, stepped in to play guitar for TIA during early '06. At the time, the band decided to stop booking shows in order to concentrate on writing new material. However, their plans were put on hold again with yet another departure; Aleks chose to leave the band in late March 2006 to pursue other endeavours.

The band continued to play their booked shows with temporary guitarists. By spring of '06, TIA had met Travis Alexander and invited him to join the band by June '06. With a final line-up, Therefore I Am was able to tour, play regular local shows and record various demos including "Farewell via Park".

The year 2006 brought not only two new guitarists and their split 7-inch, but also their first full U.S. tour, two east coast tours, and the release of the "You Are Connected" EP. They also played the Ernie Ball Battle of the Bands Warped Tour stage in Boston, MA and cut a demo with esteemed producer Matt Squire (People In Planes, Panic! at the Disco, The Used).

2007/2008

In 2007 they landed the opening spot on Rockstar's Taste of Chaos in Boston, MA, were featured in Alternative Press Magazine as a "Best Unsigned Band of the Month"^[1] and featured as one of the "Top Unsigned Bands in the U.S." on DailyChorus.com.^[2] They entered the studio with Mike Poorman (Piebald, Tsunami Bomb, Paulson) that August to record the EP entitled "Escape". At the end of the year, in support of the self-released EP, they went on a small tour with Vanna, then shortly after with As Tall As Lions and The Receiving End of Sirens.^[3] During 2008 they did multiple tours in support of Escape, played The Receiving End of Sirens' final shows with Envy on the Coast in Providence, RI^[4] and Hit The Lights in Allston, MA,^[5] then on August 20, 2008, they announced that they had signed with Equal Vision Records.^[6]

2009

The band finished recording their Equal Vision debut in early 2009 and announced they would be playing the entire Warped Tour via the Skullcandy Stage. They then went out on a month-long tour through the Pacific Northwest with Confide, Oceana, and To Speak of Wolves. In March they were featured on the Warped Tour website as one of the band "Kevin Wants You to Know" by Warped Tour owner Kevin Lyman.^[7]

Their Equal Vision Records debut The Sound Of Human Lives was released on June 23, 2009. The songs "Splinters" and "I Am Only An Island" can be heard on their Myspace, and "I Am Only An Island" can also be downloaded as a part of the Equal Vision Records sampler on the Equal Vision website.^[8]

On December 9, 2009, Therefore I Am released a video for "I Am Only An Island."

On February 2, 2010 "I Am Only An Island" premiered on MTV2's Headbanger's Ball.

Break-up

On September 22, 2010, Therefore I Am announced their decision to break-up. They haven't released any reasoning to it other than it being for personal reasons. November 20, 2010, will be the band's final show.^[9]

This was their latest statement on the break-up.

I met Alex, Brian, Chris and Jim on Pratt Street in Allston, MA during the spring of 2006. Therefore I Am played music before I came into the picture but my accompaniment marked the beginning of something new. I joined their band on a whim. I dropped out of school, bought an amp and hit the road. The aforementioned members of Therefore I Am became my family, my closest friends and my life. They presented to me several life-changing opportunities and plugged me into a social circle I wouldn’t have otherwise had the pleasure of knowing. During the better part of the 5 years we spent in a van, the 5 of us bonded, fought, partied, smiled, argued, sang along together and learned to love each other. We will always love each other. It is with great dismay that I am announcing the end of Therefore I Am. There are a lot of reasons behind our decision but we would prefer to keep them personal. We are all still friends and that’s what matters most. This was by no means an easy decision for any of us. Life changes and you must change with it, regardless of the frustrations that come with said adjustments. The 5 of us are lucky and blessed to have had the opportunities we were given. In the past 5 years, we’ve come a long way. We’ve toured with heroes, crossed oceans and did a lot of things we never thought we’d be able to do in our respective lifetimes, let alone our twenties. Most importantly, we’ve acquired a large collection of friends and created an insane catalogue of memories. To say the very least, we’ve seen a lot of stuff. We’d like to thank all of the friends we’ve made and all of you who supported us with your thoughts, floors, roofs, showers, meals, hometowns, shows, tastes and love. You were as much a part of Therefore I Am as we were. You are connected. Please join us for our final shows November 19th at the Derry Opera House in Derry nh and November 20th at Lupo’s in Providence, RI. We will be joined by some great friends and we hope to see you all there one last time.

-Travis Alexander and Therefore I Am

Therefore I Am played their last show on November 20, 2010, at Lupo's Heartbreak Hotel in Providence, Rhode Island to a sold out crowd.
