Shock Front is the first full length album by Converter, released November 22, 1999 (see 1999 in music). The album is released in two editions, the first featuring a special metal plate packaging (now deleted), the second featuring a regular cardboard booklet format (still available).

In physics, a shock wave or shock is a type of propagating disturbance. When a wave moves faster than the local speed of sound in a fluid it is a shock wave. Like an ordinary wave, a shock wave carries energy, and can propagate through a medium; however it is characterized by an abrupt, nearly discontinuous change in pressure, temperature and density of the medium. In supersonic flows, expansion is achieved through an expansion fan also known as a Prandtl-Meyer expansion fan.
