We’re going classical this week. With school years ending, orchestras and other ensembles are hitting their peaks and offering spring concerts: Florida Southern at Branscomb and Southeastern University at Bush Chapel both tonight at 7:30, and Harrison School for the Arts Friday at 7. If you just want to party, check out Bully For You at the annual Lakeland Derby starting 5:30 Friday at Lake Mirror. Also, South Florida Americana duo The Reckless Saints hit Swan Brewing tonight and Friday. There’s lots more local music after the jump.
