There are at least two artists or groups known as Trapezoid. 1. Trapezoid was the musical project of Neil Cicierega before Lemon Demon. A large difference between the two is that a vast majority of Trapezoid's songs were instrumentals, with a few exceptions. Soon after Neil moved on to Lemon Demon he was contacted by a previously established band by the name of “Trapezoid” (which is most likely the second band on this page), who claimed copyright to the name thus Neil remained the now defunct music project "Deporitaz".
