It's a little bit before Valentine's Day, but we defy you to not get in the mood early at Hot 92.3's Love Affair. The bill features R&B touchstones the Intruders, Bloodstone, the Impressions and seven others. If you don't walk out of this having earned some smooches, you must have really messed up. Gibson Amphitheatre, 100 Universal City Plaza, Universal City. 8:15 p.m. Fri.-Sat. $25-65. http://www.Hot923.com.
