Record Store Day is an annual event, started in 2007 and held on one Saturday every April, to celebrate the culture of the independently owned record store. The day brings together fans, artists, and thousands of independent record stores across the world. A number of records are pressed specifically for Record Store Day, and are only distributed to shops participating in the event. Starting in 2015, Twenty One Pilots have released a specially produced record for each Record Store Day.
The LC LP is an extended play released by Twenty One Pilots in April 2015. The EP is available only in vinyl and was produced specially for Record Store Day 2015. The record was a limited release of 4000 Ohio shaped red vinyls. The EP is three tracks long, featuring live versions of songs from the album Vessel, as well as one track from the first album. After selling out on Record Store Day, the band released 500 to be sold on their website, which sold out the same day.
