From a serendipitous jam in Berlin to the sun-drenched plains of El Paso, Whose Hat is This? has woven a sonic tapestry fueled by improvisation, flavor and unhindered talent.

Their story begins, fittingly, with a question. JJ Johnson, the band’s enigmatic drummer, found himself staring at a ten gallon cowboy hat perched on a tom during a late-night jam session at Berlin’s A-trane. “Whose Hat is This?” he called out, the question becoming their moniker, an apt symbol for their embrace of the unplanned and the unexpected.

That night, two hours of untamed musical exploration unfolded, captured unknowingly on tape. The raw energy, the fearless interplay, it begged to be shared. Thus, their self- titled debut, a vinyl-only gem, was born.

KOKAYI was weaved into the fabric of their improvisations, leading to “Everything’s Ok,” a second live album recorded at Baltimore’s 8×10 club. With KOKAYI on board, the musical conversations came vocal as well, and the band’s East Coast tour cemented their reputation as pioneers of sonic spontaneity.

Ponyboy, their debut studio album, released in April 2024 on Heartcore Records is a snapshot of their current journey, a testament to the electrifying spark that ignites when musical minds collide without a map, an homage to the days when the innocence of not knowing birthed innovations and a passion for discovery.

Tim Lefebvre
Throughout his wide-ranging career, Tim Lefebvre has amassed a reputation for being one of the world’s most innovative bassists. The Foxboro-native’s creative playing style is an addictive blend of jazz improvisation, rock undertones, and electronic grooves that can be heard on his appearances on over 150 recordings, ranging from Grammy award-winning albums such as David Bowie’s Blackstar to the soundtracks of classic films such as The Departed. From 2013 to 2018, Lefebvre was the bassist of the dynamic blues rock ensemble Tedeschi Trucks Band, and he can be heard on their three most recent releases, Let Me Get By (2016), Live From The Fox Oakland (2017), and Signs (2019). Before joining the group, he worked with artists such as Wayne Krantz, Chris Botti, and Leni Stern. Now based in Los Angeles, Lefebvre is currently the bassist for numerous groups, most notably with improvisational free-jazz group Whose Hat Is This? and with his Blackstar bandmate Donny McCaslin. He has recently performed with Chris Potter, Jon Batiste and Stay Human on The Late Show with Stephen Colbert, Empire of the Sun, Carole King, Ben Platt, Knower, and Matisyahu as well. Lefebvre is also the producer for a diverse range of projects, which includes singer-songwriter Rachel Eckroth’s album When It Falls (2018). Through all of these experiences over the past two decades, Lefebvre has constantly expanded his musical artistry, discovering new sounds for the bass guitar and influencing a generation of musicians along the way.
