Some bands are made up of those who fled organized education at the first chance possible, while others are just a bunch of math majors. Canasta has got to be one of the latter. Suggested by Dawntread at the University of Chicago (need I say more?), Canasta taps into a Chi-town vibe with melodic, witty and intelligent chamber-pop. For something upbeat, enjoy “Slow Down Chicago,” and glide along with its tastefully muted horn line. For introspection, “Shadowlands” could have been written by heartbreak kings Ben Folds or Mac McCaughan, but wasn’t.
