In 2004 Wood signed a solo recording contract with Warner Music and changed the spelling of her name from Tiffany to Tiffani in order to avoid confusion with the 1980s American popstar Tiffany. The debut single, “What R U Waiting 4” re-introduced Wood back into the music scene, marketed as an organic, light pop-rock singer (similar to the likes of Michelle Branch, Alanis Morissette etc.). The tracks highest chart place reached #22 on the ARIA singles chart and was one of the most-played songs on Australian radio in that month. Along with that release came two more of Tiffanis co written tracks The Mirror and You and I, which also gained much praise.

Behind the scenes, however, tensions between Wood and Warner Music grew. Wood insisted that the second single be a self-penned track but Warner Music already planned on releasing someone else’s song as the next single. After failing to reach a compromise, Wood made the decision to leave behind her recording contract for the option of artistic freedom and ultimate career control.

In 2004 Wood was chosen to be the host of Pure Model managements Model search which travelled the nation and had great exposure on Foxtel.

In 2005, after leaving Warner Music, Wood decided to release her material independently and established her own record label Mudhoney Records. The first single “Devil in Your Soul” was released on the 18th of July and showcased a harder, fast-paced rock sound with electrical guitars, strong drum beats and a saucy vocal performance by Wood. The tongue-in-cheek lyrics, written by Wood and Richie Goncalves (who produced the song ) took a playful stab at the music industry and how major record labels can take advantage of their younger artists in order to make them ‘marketable’. The single debuted at #13 on the A.I.R chart ( Australian Independant Records) and spent numerous weeks in the top 20.

In April 2006, Wood released her second independent single “Spin the Bottle” with a number of promotional commitments including a performance on the Seven Network’s top-rating breakfast television programs Sunrise and Mornings with Kerrie Anne. The song also featured in promotions for long-time Australian soap Neighbours in the lead up to the 2006 TV Week Logie Awards. The single was a success on the AIR charts, debuting in the top 5 and eventually peaking at #2.

Wood has established a strong reputation for her live performances, headlining shows at nightclubs and numerous events across the country so in 2006, she put together a burlesque-styled show, drawing inspiration from the 1940s and Dita Von Teese for her latest look and style of performance.In September 2006, she released an up-beat cover of the Divinyls 1990 number one hit “I Touch Myself”, receiving positive reviews. The single peaked at #5 on the AIR charts and was performed on the ARL Footy Show which at the time Tiffani found out she was 3 months pregnant with her first child.

Her debut solo album Bite Your Tongue was released in October 2006 and features a collection of self-penned rock-pop songs touching on issues such as body image, falling asleep behind the wheel and the entertainment industry. Respected music critic Cameron Adams gave the album three stars out of five, crediting Wood for her “powerful voice” and describing the record as “sassy”. But because of the unexpected pregnancy Tiffani didn’t get the opportunity to promote her album and instead turned her focus on the impending birth of her daughter.
