Low Key Piano Bar is closing its doors in downtown Tempe after one final weekend, ending a 12-year run as one of Mill Avenue's most beloved nightlife destinations. The dueling piano bar, tucked into a subterranean suite at Mill Avenue and Fifth Street, will play its last song Sunday, according to a social media announcement the venue posted this week.
The closure caps a run that began in 2014, when the space was rebranded from RCK CTY into Low Key Piano Bar, as reported by Phoenix New Times. The venue did not specify the exact reason for its closure, but in its announcement it told guests, “It's time for us to play our final song,” adding that the bar was “more than a piano bar” and had provided “a place where strangers became friends and celebrations became memories.” Low Key thanked everyone who requested songs, sang, celebrated, tipped entertainers, or simply walked through its doors over the years.
Low Key was operated by Amplified Hospitality Group, a business partnership formed in 2014 by father-son duo Kenny Walter and Austin Walter specifically to launch a modernized take on the dueling piano bar concept. The format itself followed a nightly formula of rock and pop hits turned into crowd singalongs, a style the bar carried on from its predecessor at the same address, drawing what the venue described as thousands of voices around the piano night after night.
A Basement With Deep Roots on Mill Avenue
The underground suite at 501 S. Mill Ave., Suite B-101, has hosted nightlife under various names since the 1990s, including a run as Beeloe's before it became The Big Bang in 2003. That venue launched after Tempe passed a municipal smoking ban that opened up commercial vacancies along the corridor, according to Billy Ward Music, which co-founded The Big Bang alongside partners. The Big Bang ran for 11 years before closing in September 2014, when the space briefly became RCK CTY before Low Key took over later that year.
Longtime Phoenix pianist Mikey Clavijo served as Low Key's Entertainment Director after spending a decade performing at The Big Bang starting in 2003, per MikeyC Music. Clavijo also helped open both the Tempe location in 2015 and a second Low Key outpost that opened at Glendale's Westgate Entertainment District in December 2018. That 9,200-square-foot Glendale location operated until 2021, when it closed and was later replaced by Tulum Modern Kitchen & Cocktails in 2022, according to mouth by southwest.
The dueling piano concept didn't stay confined to Arizona, either. Low Key owner Austin Walter partnered with original Big Bang founders Sam Leatherwood and Meredyth Muller in August 2024 to open Pete's Dueling Piano Bar in downtown Nashville, a venture that merged the two brands into a single operation, according to Pitch Candy PR.
Fans Flood Social Media With Memories
News of the closure sent longtime patrons to social media to share memories following the announcement Wednesday. One Instagram commenter recalled going to The Big Bang starting in 2011 and said Low Key had revived that old format when it took over the space, while another wrote that they had asked out their now-wife at the venue.
What Comes Next for the Mill Avenue Corridor
Low Key's exit adds to a wave of change reshaping downtown Tempe. The city is in the midst of its first full streetscape renovation along Mill Avenue in more than 40 years, a project that included hoisting a 36,300-pound marquee “MILL AVE” sign near Fifth Street in April, as Hoodline reported at the time. Nearby, the city spent more than $500,000 to relocate the 123-year-old Harry Walker House to Fifth Street last year to clear space for a 30-story mixed-use tower, with plans to turn the historic home into a local ice cream shop.
New nightlife concepts are also moving in as older, student-oriented bars depart. RePUBLic Tempe, a hybrid sports bar, live music venue and cue club led by local operator Scott Price of nearby C.A.S.A., is slated to open on Mill Avenue this month. The corridor also saw a brief public safety scare in March, when Tempe police shut down Mill Avenue between Third and Fifth streets to investigate a weekend shooting near the Fifth Street intersection.
Whether the dueling piano format returns to Mill Avenue, or resurfaces elsewhere in the East Valley, remains an open question. For now, Low Key Piano Bar's basement stage falls silent this weekend after 12 years of singalongs, closing out a run at 501 S. Mill Ave. that traces back to The Big Bang's opening in 2003.
