Mark Hoppus (Blink-182) and Sean Mackin (Yellowcard) will be guests on tonight's season finale of "Full Frontal" on idobi Radio hosted by Alex Gaskarth and Jack Barakat of All Time Low. Tonight's season 3 finale will be a 2-hour special, airing at 7pm EST. Mark has said he'll be discussing his new project Nothing and Nobody and Blink-182.
Edit: I'm excited to hear what Sean has to say about the new Yellowcard album. They seem excited about it. Probably my most anticipated release of the year behind Gaslight Anthem (and 3eb if they're actually going to release something).
