Blazers coach Nate McMillan was frustrated his team never established any defense.
"We have to be hungry," McMillan said. "They have guys who stepped out on the floor tonight who are trying to make teams, make that team, or trying to get playing time outscrap us and outwork us."
Andre Miller led the Blazers with 25 points and six assists. Aldridge added 20 points.
The game at Memorial Coliseum was held as part of the Blazers' season-long 40th anniversary celebration. Portland was awarded a franchise in 1970 and the team played at the so-called "Glass Palace until 1995.
The Suns were the last team to visit the building, for a first-round playoff game on May 2, 1995. Phoenix won 109-117, led by Charles Barkley's 47 points.
Among those at Wednesday night's game were team founder Harry Glickman, former players Jerome Kersey, Terry Porter and Bobby Gross, as well as broadcaster Bill Schonely, who coined the phrase "Rip City." The Schonz, as he is known, called the second half of the game on the Blazers' flagship radio station.
"I think it's appropriate tonight to recall Bob Hope's theme song: Thanks for the Memories," Glickman said.
To mark the event, the Blazers wore throwback Rip City jerseys.
The Blazers won 54 games last season as the second-youngest team in the NBA. They fiddled with their roster a bit in the offseason, adding experience in Miller and Juwan Howard, and are hoping to take the next step after returning to the postseason.
Phoenix failed to make the playoffs last season for the first time since 2004, going 46-36 in a tumultuous year that saw Porter fired at the All-Star break and replaced with assistant Alvin Gentry.
