Site-specific installation commissioned by Berkeley Investment for their new residential building at 3200 Washington Street, Jamaica Plain in Boston. One of the requirements from the commissioner was the connection of the artworks with the place where the building is located. Between 1901 and 1987 the Boston Elevated Railway also known as the ‘EL’ used to transit on the same road where the building is located. The EL was one of the first elevated electric transit railroad of the nation. The presence of the EL also changed dramatically the space where it used to transit by trading off light for the closeness to the city. Nowadays almost no sign has been left to testify the presence of the EL. Therefore the conceptual drivers for this work relates to the ideas of ‘memory’,  ‘absence’, ‘discovery’,  ‘movement’ and time. The disconnected railway-like structure, and the use of mirrors reference the ideas of memory and absence/presence. The colored bands recalling stereotypical chromosome images from scientific publications feature the idea of discovery but also my work as bio-researcher. The titles of the artworks reference ‘time and movement’ using a music terminology, describe the ‘mood of the composition’ and the dynamic and EL’s transitory nature
