A year has passed since the takeover of the club by a group of investors.
Bruno Guimaraes put the ball in the air before Jacob Murphy made the score 2-0.
Ivan Toney scored a penalty against his old club, but Guimaraes scored again less than a minute later.
Almiron and Pinnock scored their own goals.
The ball was in the back of the net when Bryan Mbeumo slammed it through Nick Pope's legs. The effort was ruled out by the VAR after Toney moved out of the way of the ball.
Guimaraes headed home after Trippier brilliantly curled in a far-post cross from deep.
A howler from Raya led to a second lead for the team. He was playing square for Murphy to hit the ball.
Guimaraes restored the two-goal advantage as he won the ball near the halfway line, drove forward and struck to Raya's right from close range.
Pinnock sold Raya short with an under-hit pass that Almiron burst on to and slammed home as the Bees were caught playing out from the back again.
Pinnock stuck a boot out in front of Raya to allow a low cross from the left to find its way past him and into the net.
One year and a day after a Saudi-led consortium took over their club, the fans were happy. The takeover announcement and the signings made in the past year were covered by a Tifo before the start of the game.
The two players signed by the current owners are Trippier and Guimaraes. Trippier's crossing reminded him of why he may go to the World Cup with England instead of Trent Alexander-Arnold.
Guimaraes was the driving force in the middle of the park for Eddie Howe's side.
After five minutes, Almiron forced a great save from Raya, he was an energetic attacking presence, and he continued in that form after the break.
After scoring his fourth goal of the season, he was presented with a flag from the crowd, a sign of the esteem in which he is held by fans.
The return of Allan Saint-Maximin as a late substitute capped a great day for the team, the forward having not played since August because of a injury.
There was a VAR-crushed moment early on that never looked likely to end the sequence of wins for the Bees.
The goalless draw at Bournemouth was their first clean sheet of the season. Thomas Frank has issues to solve in defence.
It was a bad day for Toney, who captained the club at the stadium where he made two substitute appearances for the north-east side in the top flight.
Toney scored with his 21st successive converted penalty early in the second half after inadvertently denying his side their opener.
It is at the other end of the field where their major problems lie and he has been involved in eight of the 16 goals they have scored.
