Davie504

Biale began playing bass in high school after being influenced by Kiss bassist Gene Simmons.[5][6] In 2011, he created a channel named Davie504, and began to upload unconventional cover performances of songs in 2012.[7] Examples of these videos include him using M&M's to cover songs by Eminem,[8] a Korn medley played with corn cobs,[9][10] and a Red Hot Chili Peppers medley played with actual chili peppers.[11] He also performs musical challenges, which are often suggested to him by comments on his videos, such as playing an uninterrupted slap bass solo for 5 hours,[12] and playing a bassline which Deadmau5 claimed to be "technically impossible".[13]

Biale is also known for uploading meme-related videos and covers. Most notably, he contributed to the PewDiePie vs T-Series competition, where he played a bass cover of "Bitch Lasagna" outside of the T-Series headquarters as well as a video series where he reacts to posts made on his subreddit page.[14][15] He also participated in a competition with Jared Dines and Steve Terreberry to play the guitar with the most strings.[16][17]

The number '504' in his nickname is a reference to his day and month of birth, 5th of April.[3]

In 2017, Chowny Bass released the Davie504 signature bass guitar.[18] In May 2019, Biale was listed as number two on MusicRadar's list of "the 20 hottest bassists in the world today".[19] He received his Youtube Gold Play Button later that year, which he turned into a custom bass alongside Amnesia Guitars.[20]

In 2021, Biale was featured on the cover of Bass Player.[21]

In February 2023, Biale performed in a music battle against YouTubers TwoSet Violin at The Star Performing Arts Centre in Singapore, continuing an on-screen feud with the duo since 2020. It was his first-ever live performance.[22]

Biale grew up in Albisola Superiore of Savona, Italy.[3] He attended the University of Genoa before dropping out to focus on his YouTube career. He later studied music production at a college in London. He moved to Brighton in 2017.[23]

Biale's wife, who is also a bassist, is indigenous Taiwanese.[24] They met after she viewed Biale’s content online and connected with him. They were married in October 2022.[25] He lived in Taiwan during the COVID-19 pandemic before relocating to Italy in 2022.[26][27] In a 2013 Q&A video, Biale cited Flea, Gene Simmons, Marcus Miller, Victor Wooten as some of his favorite bass players.[28]
