Logroño obtained a Bachelor of Arts (English Language Literature) degree ("a degree in unemployment", Logroño claims) from the University of Puerto Rico at Río Piedras and a Master of Arts (Theater) degree from Michigan State University. After his return to Puerto Rico, Logroño was a member of the Puerto Rican folk group, "Moliendo Vidrio", which also starred bandleader Gary Nuñez and later comedic actress Carmen Nydia Velázquez. Moliendo Vidrio made a few albums during the 1970s. By the late years of that decade, the group disbanded.
