Leave a Safe IT Job for Music Tour?

DecisionTime asks: "In this US economy, it took me a whole year to find my current IT job, where I've been for less than a year. It's fairly dull, but pays ok, and I believe it is relatively safe. Now, I've been given the chance to use my talents and tour full time with a band overseas. With the corresponding drop in expenses, my net income on this tour would remain about the same as now. However, music jobs are inherently risky, yet the touring could become long term. On the other hand, I could potentially be IT job searching again within four months with a dubious hole on my resume. I'm single and have no kids or major commitments, but I do not want to destroy my IT career either for the future. I can't get unbiased advice where I am, so perhaps Slashdot can lend me some wisdom?"
