BIOGRAPHY
"Stefano Valli is an Italian singer and songwriter. He is most known for his work with the group Pooh, with whom he released multiple albums and singles."*
*Note: It is stated that Stefano Valli is known for his work "with" the group Pooh, rather than "within" the group Pooh. This implies that he may not have been an official member of the group, but rather a collaborator. If he was an official member, the sentence would be rephrased to reflect that information.
