Nicolas has 1 Madi Diaz concert.

Madi Diaz (born May 14, 1986) is an American singer-songwriter and musician. Raised and home-schooled in Pennsylvania's Lancaster county, she is the daughter of musician Eric Svalgard (keyboards in the noted Frank Zappa cover band Project/Object) and schoolteacher Nancy Diaz. Encouraged by her parents, Diaz began commuting to Philadelphia in 2002 to attend The Paul Green School of Rock Music, where her father volunteered (today her father runs the Wilmington, DE, branch of the school, where Diaz's brother Max is also an instructor).
