Some groups within the CWLU focused specifically on women's involvement in music and the arts. The Chicago Women's Graphics Collective was first organized in 1970 to provide high quality feminist posters for the growing women's liberation movement and to encourage women in the arts. The Chicago Women's Graphics Collective originally used silkscreen to create their large brilliantly colored prints because it was inexpensive and posters could be produced in member's apartments. The Chicago Women's Liberation Rock Band was formed in 1972 and focused on women expressing themselves through their musical talents.
