Mr. Plow just can’t stop succeeding.

By the beginning of last summer, they had conquered the cornfields of central Iowa — at least the ones surrounding Ames.

In June, they were flown, all expenses paid, to Los Angeles to do a record label showcase for Warner Bros. Records and to play for Capitol Records executives as well. They stayed longer than planned.

And last week, the local favorites went national when they caused their funkblasto sounds to ring in the heads of about 150 attendees of the CMJ Music Marathon in New York City.

“It was really fulfilling,” Sam Johnson, Plow bassist/rapper, said. “It was the first time our music had brought us coast to coast.”

Soon after midnight Oct. 19, the band took the ASCAP showcase stage at the Shine Club on West Broadway. Fighting against poor sound monitors, Plow played an intense half-hour set to a diverse crowd — general bar patrons, music fans and A&R representatives from labels such as Warner Bros., RCA and Dreamworks.

The reactions of the record executives — polite clapping and slight head-bobbing — were a far cry from the usual responses the boys get in Ames from 15-year-old girls who scream and jump around every time one of the Plowstreet Boys smiles or says anything.

“We’d get done playing a song, and normally where there’d be people going crazy, there was complete silence,” Johnson said. “All you hear is the amps buzzing.”

However, Johnson said the band felt well-prepared for the gig, largely due to the guidance of the band’s co-manager and former 35″ Mudder bassist, Chad Calek.

Even though the suits seemed relatively unenthusiastic — common at showcases, according to Calek — the show was not without energy and excitement. The band played solidly and even got some people moving to the music.

“They had a whole group of girls and a couple guys dancing around — primarily girls, which I think is a Plow trademark,” Calek said.

The band was a little surprised by the response from the New York crowd, a group of music listeners Calek calls both “traditionally brutal” and “a fucking animal.”

“I think there was like three girls in the crowd that, the whole time, were just jumping, jumping up and down,” Dan Fjelland, Plow rapper, said. “And you don’t see that much, especially in New York, especially with people that, for the first time, just saw you.”

Not all of the concertgoers were experiencing Plow for the first time, however. President of Warner Bros. David Kahne, who had produced a song with the band in L.A. this summer, was on hand to see the sextet perform.

“He gave me a pat on the back and told me, ‘Good job,'” Fjelland said.

Months of practice and preparation had paid off.

“The band is from Ames, Iowa, and they’re in the hottest club in New York playing for a president of a record label,” Calek said. “You can’t really lose in that situation. [CMJ] is as huge as it gets for an unsigned band.”

Plow was chosen from the thousands of bands associated with the American Society of Composers Authors and Publishers — a company that works on artist development — to headline the ASCAP showcase, which featured a total of five bands.

The band owes Craig Pizella, from Warner/Reprise, for the opportunity to headline the showcase. He had met the band in L.A., becoming their friend while hanging out with them. Pizella became a strong supporter of the band and sent a Plow press kit to Courtney Hard, the person responsible for organizing the ASCAP gig.

“She loved it, so she booked us for the show,” Johnson said.

At least seven label representatives were present to see Plow, though the band members have yet to hear any word of deals in the making. This is not unusual, however.

“There could have been somebody there who loved them more than life itself, and they would’ve never told them. [A&R representatives] never tell them,” Calek said. “They go back in their offices, they lock their doors, they play the role of the big shot and they kick it around. The important thing to remember in these showcases is that they’re not looking for a reason to sign you — they’re looking for a reason not to sign you.”

It will still be a few weeks before the band hears anything regarding record deals or label reactions to the showcase.

In spite of this, Plow didn’t spend their time in the Big Apple worrying about record deals or stressing that they “couldn’t screw up.” They caught a Knicks game, hung out with Glen Naessens — a former “Real World” cast member whom they had met while appearing in Calek’s film, “The Private Public” — and made a surprise appearance on “Saturday Night Live.”

The band was in Times Square one evening — Wednesday or Thursday, they can’t quite remember — when they decided to grab some pizza at 78th and Broadway. Then, they noticed a television shoot going on nearby.

Someone from the film crew noticed Plow and asked them if they wanted to be part of a skit for the “Weekend Update” portion of “Saturday Night Live.”

“We signed the papers, and next thing we know, we’re chasing behind a van, screaming,” Johnson said. “It was like our three-and-a-half seconds of fame, but it was still fun. [Plow drummer] Ubong’s hair is flying everywhere. But I’d rather be on the show as a musical guest.”

Fjelland said the band must have been “there at the right place at the right time,” a position the band seems to have been in a lot lately and something that could allow them to earn the coveted “SNL” slot.

Plow appears to be making all the right moves to ensure that someday more than just Ubong’s afro will appear on the sketch comedy show.

“In the end, that band’s going to succeed no matter what,” Calek said.

And the band has realized they need to make a conscious decision to be successful, something that is evident in their efforts to spread their music from coast to coast and across cornfields.

“We’ve always been in the band just because we love music, which I think is great — you can’t be in the band just for the business,” Johnson said. “But now [in light of CMJ and the L.A. showcases], it’s like our fun and our music and our love is becoming our business, and it is time to realize that and for us to take the next step …I think we’ll really elevate our band to the next level.”
