<strong>Toad The Wet Sprocket:</strong> All I want is for you to go to this show and remember what it was like to love alternative music of the early 90s. The band, who was named after a fictional band in a Monty Python sketch, came together in 1986 as teenagers, releasing their first album in 1989. But they didn't gather a true following until their third album, 'Fear,' in 1991. The rest is history. Now they're regulars over at Uptown Theatre in Napa, where they'll be performing a make-up concert for the one they had to postpone in February, with special guests Tommy and the High Pilots. Tickets for the 8 p.m. show are still available for $37-$47, plus fees. Info: <a href="http://www.uptowntheatrenapa.com" target="_blank">www.uptowntheatrenapa.com</a>
