Launch Radio Networks reports: STAIND began its winter North American tour this past weekend and singer Aaron Lewis admits that the hardest part is being away from his family. Lewis and his wife had their second daughter in June of 2005, and Lewis told Launch it was difficult to leave her for the first time last November on the Fall Brawl tour. "When my wife sends me pictures, and the first batch of pictures that I got once I was out here was probably three or four weeks after I left, and I didn't recognize my daughter, that was a little bit hard to deal with," he said. "You know, they change so quickly when they're that young. Over that time period, she just totally filled out and it didn't look like the little girl that I had left."Lewis's daughter is named Nyla Rae. The vocalist and his wife Vanessa also have a three-year-old girl named Zoe Jane. STAIND will play at Florida's Daytona International Speedway on February 11, following the NASCAR Budweiser Shootout. The race begins at 8:30 P.M. ET and STAIND will perform immediately afterward. Tickets for the race can be purchased at RaceTickets.com. STAIND continues to support its 2005 release, "Chapter V". The band's winter trek with THEORY OF A DEADMAN and ROB ZOMBIE guitarist John 5's new act, LOSER, pulls into Portland, Maine on Saturday (February 4). The jaunt finishes up on February 19 in Minneapolis.
