SDMusic TV will host a battle of the bands at Brick by Brick on April 4. While most such contests are usually loaded with bottom-of-the-barrel bands or up-and-comers trying to make a name for themselves, this time out, the folks at SDMusic have put together a solid bill, including terrific guitarist Roni Lee, best known as writer for the Runaways’ classic, “I Wanna Be Where The Boys Are;” indie rockers Special Delivery and alt-rock quintet Mad Traffic. The latter is particularly worth catching. Led by songwriter and charismatic frontman Blaisé Guld, the group has a slew of great tunes, like its latest single, “Open Door.” Come on down and cheer on your favorites or find a new group to champion, but this is one contest that may just deserve to have more than one winner. • Mad Traffic: Thursday, April 4 at Brick by Brick, 1130 Buenos Ave. 8 p.m. 21 and up. $10. www.brickbybrick.com
