SWAG

Promotional merchandise for a band, record label, or other entity in the music business, usually distributed at concerts.

May include t-shirts, stickers, promo CDs, posters, etc. Often free, but not necessarily; a t-shirt or record purchased at a concert might still be considered swag, especially if it is a design or release that is not readily available in the mass market.

Many independent record labels throw in a handful of free swag when they ship out mail-order packages (stickers, sampler CDs, etc).
