Born in Valletta, Pawlu grew up in the neighbourhood of Id-Due Balli, a working class area of the Maltese capital city.

Son of Frankie Camilleri Il-Bibi, a noted Maltese jazz musician, and brother to drummer Joe Camilleri, Pawlu has released a number of religious albums, including Jesus' Words in 1995.

Two songs, "Min Jiġi Għandi" and "GĦidli Ħabib", were already performed during concerts.

He has featured on harmonica in Dominic Galea's jazz album Tribute, Andrew Cauchi's Bil-Qawwa ta' Mħabbtek and in both of Walter Micallef's albums, M'Jien Xejn and Ħamsin.

Camilleri sings regularly at correctional facilities and drug rehab houses in Malta, with his themes focusing on songs of courage and praise of Jesus Christ.
