The poster child of hip-hop’s mixtape era, Freddie Gibbs (pictured) left Interscope Records before putting out his debut, finding success instead through a series of unofficial, unflagging Internet-only EPs. A long-awaited long-player is expected in 2012 on Atlanta imprint Corporate Thugz Entertainment — whose CEO, Young Jeezy, headlines this tour. Tickets $37. midnight Sunday. House of Blues, 225 Decatur St., 310-4999;
