Blues on the Green with Bob Schneider and Walker Lukens at Zilker Park. Cross your fingers for dry days: The first two Blues on the Green concerts of the season had to be rescheduled when rains wreaked havoc on the Zilker grounds. Weather permitting, the omnipresent Bob Schneider, fresh from an orchestral gig with the Tosca String Quartet earlier this month at the Long Center, will stretch out with a broader repertory, with rising local talent Walker Lukens opening. Free. 8 p.m. 2100 Barton Springs Road. kgsr.com/botg. — P.B.
