Flo and Eddie are one of the many hit 60s acts playing with the Hippie Fest tour this summer, which hits Wolf Trap on Tuesday. Photo from Paradise Artists.

MONDAY
>> Here’s a good reason to spend the hottest day of the summer in a cool, dark place. Franz Nicolay, he of thee immaculate Rollie Fingers mustache (oh, and of thee Hold Steady), comes to the Black Cat backstage in support of his recent solo record, Major General. Joining him on the bill is TV Torso, made up of former members of the Sound Team. $10, 9 p.m.

>> Three Stars alums The Beanstalk Library open up for the lovely Jenny Owens Young at the Iota Club. Her new album, Transmitter Failure, is just out and she’s hitting the eastern seaboard in support. $12, 8:30 p.m.

TUESDAY
>> Can we agree that this Woodstock-40th-anniversary has taken ’60s nostalgia a little too far? Wolf Trap features Hippie Fest on Tuesday night, a massive bill full of hit 60s acts with amended names to avoid lawsuits and/or inflate egos. For example: Mountain, featuring Leslie West and Corky Laing (riiiight); Chuck Negron, formerly of Three Dog Night (the other dogs tour without him and excluded him from the band’s bio); Flo and Eddie of the Turtles, who I would actually like to see; Felix Cavaliere’s Rascals (certainly no longer “Young”, and without Dino Danelli on drums, frankly not worth it); and Badfinger featuring Joey Molland (if you want it, here it is, come and get it, by all means). All the groups tour with pretty tight backing bands that keep their hits afloat, but keep expectations low, folks. $42 in house, $25 on the lawn. 8 p.m.
