Large Professor is one of the true geniuses of hiphop. Born up in Harlem, and once a member of Main Source, Large Professor is a solid rapper and an amazing producer. He contributed three tracks to Nas's Illmatic and associated with the main players (DJ Premier, Q-Tip, Pete Rock) of hiphop's silver period (1993 to 1997). His latest record, Main Source, is an example of what "anti-fakin'" means. Indeed: "I just want to chill and put my hand around a $100 bill." (Nectar, 412 N 36th St, 632-2020. 9 pm, $10, 21+.)
