In late 2004, Ocean Avenue was certified double platinum by the RIAA, and singles such as "Way Away," "Only One," and the title track continued to impact MTV and Top 40 radio for the rest of the year. The same year, Lewis was given his walking papers when Mosely approached the band about rejoining. Yellowcard's sophomore effort, Where We Stand, was reissued in June 2005, and Lights and Sounds was released in early 2006. Though ultimately not as well received by fans as prior albums, upon its first week of release, Lights and Sounds entered the Billboard 200 at number five and earned the number one spot on the Alternative Album chart, quickly gaining momentum on the 2.5-million-selling Ocean Avenue. Meanwhile, founding member Harper (who also runs Takeover Records) left the group amid some band controversy and was replaced by Staring Back guitarist Ryan Mendez.
The band returned to the studio later that year and got to work on its fifth full-length, Paper Walls, which was released in July 2007. In 2008 the bandmembers announced they would be going on an indefinite hiatus, leaving Capitol Records. After recharging their batteries for a couple of years, Yellowcard signed with Hopeless Records and in 2011 released When You're Through Thinking, Say Yes. In 2012, Yellowcard returned with their eighth studio album, Southern Air. Featuring guest appearances from All Time Low's Alex Gaskarth, Hey Monday's Cassadee Pope, and We Are the In Crowd's Taylor Jardine, the album included the singles "Surface of the Sun," "Awakening," and "Here I Am Alive." ~ Johnny Loftus, Rovi
