The second weekend of Austin City Limits Music Festival (ACL Festival) is upon us at Zilker Park beginning tomorrow at noon. For once, it looks like there will be no rain this year (fingers crossed). Here's to hoping that prediction rings true on Monday morning. You are likely asking yourself (if you're a regular reader of this column) why read a weekend two preview when most of the lineup is similar to opening weekend? The answer is simple. We now have the benefit of hindsight. We can look both back to last week and forwards to this weekend's slate of music and intelligently choose our weekend two lineup. It sounds scientific when we say it like that doesn't it?
