NILES — By day, Jan Trapani, of Bridgman, tends to patients who need her care at Lakeland Hospital in St. Joseph. But when Trapani is not dressed in scrubs, she is stationed at her drum kit, helping to keep an era of rock and roll alive and well with fellow musicians in the band PastTime.

“We are a 50s and 60s band,” Trapani said. “That music is not heard too much over the radio. Our goal is to bring these songs back to peoples’ consciousness. We find that it really is a great experience, and when you look out in the audience and see people singing the lyrics, dancing … that is what we look forward to doing.”

This Thursday those who visit Riverfront Park will have the opportunity to take part in that revival, as the PastTime band takes to the stage for the Summer Concerts in the Park series. The band will play at 6 p.m. on the amphitheater stage. The concert is free and open to the public. Those interested are invited to bring out their lawn chairs and blankets to enjoy the music.

As all concerts in this series have done, PastTime’s performance will help to benefit a local nonprofit. This week, proceeds from the event will serve Honor Flight. Through Honor Flight, American veterans have the opportunity to be flown to the war memorial in Washington D.C.

While Trapani said Caryn Adler, the Summer Concerts in the Park event organizer, suggested the nonprofit, the cause is also one that is close to the bandmates’ hearts. Their bass player and vocalist is a Navy veteran. The band also frequently plays for veterans organizations.

“I told her we were very interested in veterans,” Trapani said. “She said she had a group … and I said ‘sign us up for that.’”

Trapani hopes that those who attend will hear songs they recognize and want to sing along.

PastTime covers a variety of rock and roll songs, and Trapani said the audience is likely to hear something they recognize like “Mony Mony,” by Tommy James and the Shondells; “Runaway” which was first performed by Del Shannon and instrumentals like “Secret Agent Man.”

“These are songs that are virtually not being played or not heard anymore,” Trapani said. “These are the originals.”

PastTimes is made up of five total bandmates, who first started rocking in 2011. Like Trapani, the musicians have varying jobs by day but dedicate time to playing music.

Guitarist Jeff Noel started the band with the goal of paying homage to his father Bill Noel’s band, The Princetons, a Benton Harbor-based group. While the band still pays tribute to this original influence, they have added a few numbers to the repertoire.

“We have expanded our musical interests to include many artists of the 50s and 60s,” Trapani said. “Doo-wop, rockabilly, soul, rhythm and blues, Motown, country.”

With the chance to listen to what some would refer to as timeless rock and roll, Tarpani said she would encourage people to visit the park Thursday for the concert.

“Number one, we are a darn good band,” Trapani said. “It is a time to hear music that we all know and all grew up with on our transistor radios. This is the music of the Baby Boomers.”
