Please answer the following question: What is the first name of the person who was playing "non-blues-scale, non-cover-song rock" with Thompson soon after they met?  Answer the above question based on the context below:  Santiago was born in Manila, Philippines, on June 10, 1965, the third of six sons of an anesthesiologist. In 1972, when President Marcos declared martial law, the family immigrated to the United States. After two years in Yonkers, New York, the family moved to Longmeadow, Massachusetts, where Santiago attended Longmeadow High School and graduated from Wilbraham & Monson Academy in 1983. His first experience with a musical instrument was playing a Hammond organ at the age of eight, but he never took on the instrument seriously because he had to share it with five brothers. Santiago first played a guitar at the age of nine after he noticed a classical guitar hanging on his oldest brother's wall for decoration. The first song he learned to play was The Velvet Underground's "Rock and Roll".As a teenager, Santiago became interested in computer programming, naming his first program "Iggy" and his second "Pop" after punk rocker Iggy Pop. He participated in a cycle ride across the United States in aid of charity, but on completing it did not bother to collect the sponsor's money.After graduating from high school in 1983, Santiago studied at the University of Massachusetts Amherst. He remained without a major as long as the university would permit him to, but eventually chose economics. He met Charles Thompson, an anthropology student and the future Pixies frontman, after he heard Thompson and his roommate playing their guitars.  Santiago rushed home to collect his guitar, and was soon playing "non-blues-scale, non-cover-song rock" with Thompson.Santiago and Thompson shared a room at the start of the second semester. Santiago soon introduced his new roommate to 1970s punk and the music of David Bowie. He later recalled their time together in college: "Charles and I had a suite at the college dorm. We'd go to shows, I remember seeing Black Flag and Angst. Initially, I think we just liked each other. I did notice right away that he was playing music ... He'd write 'em [the songs], and I'd throw my ideas on the guitar."...
