Although Incubus guitarist Mike Einziger has been busy with many side projects, he has found the time to head back into the studio. MTV.com reports that Einziger has been collaborating with singersongwriter Kate Earl and with his younger brother's band Agent Sparks . Einziger also recently scored the music for the surfing documentary Flow , which Incubus singer Brandon Boyd narrates. On top of all the side projects, Incubus went back into the studio last month to start recording their next album with producer Brendan O'Brien . It doesn't look like Incubus is slowing down any time soon, ... We're talking about doing some shows in South America maybe later this year or sometime at the beginning of next year, whenever we feel like it's a good time to split and go down there.
