Vessel (Twenty One Pilots album)

Vessel is the third studio album from American duo Twenty One Pilots which was released on January 8, 2013. It is the band's first album on Fueled by Ramen.

Background

High-school colleagues Tyler Joseph, Nick Thomas, and Chris Salih formed Twenty One Pilots in 2009. The group released their debut album Twenty One Pilots. Both Thomas and Salih parted ways with the band in 2011. Soon afterwards Josh Dun joined the band; Joseph had been friends with Dun for around a year. Joseph first saw Dun when he was playing a show with House of Heroes. Joseph said that he "loved" the performance. The band released Regional at Best later that year. In June, the duo played their first out-of-state show to a group of 12 people. The pair soon gained popularity through a series of videos made by friend Mark Eshelman. The band played their last show as an unsigned band at the Newport Music Hall in Columbus, Ohio to a crowd of 1,800 in attendance. The band signed with Fueled by Ramen in 2012.

Browning 22 Semi-Auto rifle

The Browning 22 Semi-Auto rifle, also known as the Semi Automatic 22 or SA-22, is a takedown rifle produced by FN Herstal based on a John Browning patent. The rifle is currently produced by Browning as the Semi-Auto 22. Production began in 1914 and continued through 1974 in Belgium and production continued in 1976 in Japan by Miroku. It was first exported by FN for the American market in 1956. A close copy made by the Chinese company Norinco was formerly imported into the US by Interarms as the Model ATD. Remington manufactured a lighter weight version under license from 1919-1935 as the Remington Model 24 and then replaced it with the Model 241 Remington 241 in 1935. Except for the barrel locking mechanism the Remington Model 241 is very similar to the Browning SA-22.

The SA-22 was the first production semiautomatic rifle chambered in .22 LR caliber, and is regarded as a classic firearm. It has been offered in several "grades" of engraving and gold inlay, and is a widely collected gun, especially those manufactured in Belgium.
