Boston, the rock band that brings “more than a feeling” to the stage, headlines the Musikfest 2016 Sands Steel Stage at 8:30 p.m. Aug. 9.

The rock band, celebrating its 40th anniversary with its “Four Decades North American Tour,” will bring its classic hits to the stage as well as some new additions to the group’s set list.

Boston, launched by studio technician, producer and musician Tom Scholz, became an iconic rock fixture with its self-titled debut album, which has sold more than 17 million copies.

Boston generated hits such as “More Than a Feeling,” “Foreplay-Long Time,” “Peace of Mind” and “Smokin’,” still in heavy rotation on classic rock stations.

Boston’s second album, “Don’t Look Back,” was another chart-topper, followed by “Third Stage,” which hit No. 1 on the charts, with the top single of 1986, “Amanda.”

Boston has sold more than 31 million albums.

The band performing in Bethlehem is: Tom Scholz, lead and rhythm guitar, keyboards, backing vocals; Tracy Ferrie, bass guitar, backing vocals; Jeff Neal, drums, percussion, backing vocals; Tom DeCarlo, lead vocals, keyboards, percussion; Beth Cohen-keyboards, vocals, rhythm guitar, and Gary Pihl, rhythm and lead guitar, keyboards, backing vocals.

Pihl, vice president of Scholz Research and Development, has been with Boston for more than 20 years. From playing guitar and singing backup vocals in the band, to working in the studio, to designing the band’s website, Pihl wears many hats.

Pihl, who learned to play guitar from Jerry Garcia of the Grateful Dead, played with the Sammy Hagar Band. After opening for Boston, Pihl began talking with Scholz before joining the band in 1985.

“Someone asked me to describe Tom Scholz in four words and basically he is the smartest guy I know. He is a terrific musician who always shows up as one of the Top 100 guitar players, but also keyboards. No one else is in both. He has designed the amplifiers we use on stage and put together the first album, which was the biggest selling debut rock album ever,” says Pihl.

“One thing is for sure that some people don’t know about us is that all the sounds they hear on stage we are making. There are no tracks or prerecorded sounds that come from our band. We don’t do that. We sing all those parts, all six of us. So if we hit a wrong note, it’s us.

“We have been very fortunate that our fans tell us our concerts sound just like the record. It’s heartwarming because there are no tricks.

“If we had to sit in a living room and play the songs we’ve been playing for 40 years now we would get bored of them. But when you look out and see your fans, sometimes singing louder than yourself, it transcends this amazing feeling that you can only get at a live show.”

Boston’s most recent album, “Life, Love & Hope,” was released two years ago.

“We are always writing songs because we are musicians and that’s what we do,” says Pihl.

“To me, being in a band is like being on a team. You all have to start and stop together, work together.

“I was always one of those guys interested in the technical end. I enjoyed figuring out how to fix things and make them sound even better. I kept soldering and figuring the equipment out and since it was literally made by us, our guitar techs had no idea how it all worked. It was up to Tom and I. Nobody knows the stuff on our stage, the amplifiers we built, better than me and Tom.”
