 The way singer-songwriter Gabrielle Petrangelo tells it, she sat down to write something new on a sweltering day last summer and thought about the concept of summer losers. That's the kind of person who doesn't have a plan to get out of town during the peak heat, is maybe short on funds, and has managed to block out what a desert summer can really be like. Gabrielle admits to having been that person numerous times. So have I, and maybe so have you.
