Sources close to Summer tell us … the singer was trying to keep the extent of her illness under wraps. We spoke to someone who was with Summer a couple of weeks ago … who says she didn’t seem too bad.
In fact, we’re told she was focused on trying to finish up an album she had been working on.
Summer had an amazing voice that translated many radio formats because of her crossover appeal. She remained in the Disco genre throughout her entire career offering very few ballads or R&B specific offerings.
