The Grouch and Eligh are two names that everyone needs to know in the hip-hop world. Best known for their work with the Living Legends rap group, the two have devoted much of their time to more than 20 different projects between their solo and collaborative careers. When performing as a duo, The Grouch and Eligh revitalize the energy that was once felt when the duo performed together as part of Living Legends (The Grouch is no longer in the group). The duo are on a nation-wide tour alongside Madchild of Swollen Members, Sweatshop Union, Pigeon John and DJ Fresh. See the show at Agave in Avon on Tuesday at 9 p.m. The show is free, and for ages 21 and older.
