There are at least two artists with the name Silent Majority.

1. Silent Majority formed on long island in the mid-90's and became one of the most influential hardcore bands from the area. Tom currently sings for Capital.

2. Silent Majority was a Swiss rap and hip hop music group. Founded in 1994 they were produced by Goetz (U2,Faithless). Considered turntable pioneers at the forefront of Swiss hip-hop, Silent majority are unusual within the scene, defining themselves as "funky multi-linguals", and rap in “a mixture of English, Jamacian patois, French, Spanish and Swahili”.
The members of Silent Majority decided to split up right after the release of their last album 'Nightbloomers'.
