Alternative rock band Cake is currently in the studio working on their sixth studio album. The album has yet to be titled and is tentatively due next spring. Interestingly, the band has converted their Sacramento, California studio to operate soley on solar power. In addition to helping the environment, the band is also making a little extra money with the studio, as the city is actually buying the excess electricity. "As the value of recorded music descends into near nothing, we have the added security of knowing there will be a ten or twenty dollar check coming in each month," a statement from the band said. While the band is being recorded, fans who join the mailing list on their website will be able to download ringtones of samples of six of the new tracks. "In light of recent changes in consumer expectations, I had been thinking about releasing an entire ringtone album instead of real albums," vocalist John McCrea said. "This just seemed like a good way forward to that eventual goal."
