There's one thing wrong with Clio's debut EP "Letting Go" -- at 25 minutes, it's not long enough.

Clio, the Philadelphia trio composed of Jason Hammonds on vocals and guitar, Joe Devenny on guitars, and Chad Jenkins on drums, has created a well-polished disc full of confessional songwriting, meltingly smooth arrangements and heartache.

Hammonds drew most of the inspiration for this ambitious album from one of his past relationships. "This has been one of the most cleansing processes that I've ever been through," he said. "So much of this recording was written about the last five years of my life with someone, and the EP is fittingly titled."

Hammonds bares his soul amongst tales of apologies, healing, and moving on with a powerful voice, capturing the feeling behind each passionate lyric.

"Chad would spend a lot of time making sure I got into that 'moment,'" said Hammonds. "He'd say 'go back to when you wrote it. Go to where you wrote it. Go to why you wrote it. Then sing it.'" The result is a vocal performance of unambiguous zeal and sensitivity.

On the poignant ballad "Listen," Hammonds sings "Sometimes I love her/And other times I love her more than I should." The words convey the message adequately, but it's the delivery that drives them home. Hammonds's tortured voice confesses his emotions.

The slow-strummed "Let it Go," is heartbreakingly beautiful. As Hammonds belts out this tune, his voice swelling with emotion, listeners will feel chills from its purity and depth. The track is ineffable with its harmonious melody and genuine spirit.

"Open up and write another story/about a girl I knew, knew just what to do/She was all I wanted/then all I wanted whispered 'so long,'" sings Hammonds on the first verse. The chorus, "Still we try, and I hold/Still we try, to let it go," is sung so honestly that listeners will peer into Hammonds's soul and lose themselves in the music.

"Let it Go'" began as a song titled "Me and Myself" with only one verse. Before recording it in the studio Devenny thought Hammonds should add another half.

"It just hit me one night, at the coffee shop, and out came the first verse, which really sets the whole tone and story of the song," said Hammonds. "And once that came out, and I got home and sang it for the first time … man, I had these really cool goose bumps, like I knew that it was finally complete and basically summarized those five years into a six minute song."

While the majority of the EP is about the demise of a relationship, "Let the Music Play," is an upbeat, energetic song about the freedom music lends. "Let the Music Play" is the one song of release," said Hammonds. "It's really the one song that says drop all the drama, raise your arms in a 'V' and just shout freedom."

Influenced by legendary musicians from Mike Kennealy to Jeff Buckley, the band's sound is a tight mix of infectious rock, intricate guitar hooks, catchy rhythms and dramatic drumbeats which back Hammonds's gifted voice nicely.

The vocal strength and moving music behind the emotion-packed "Letting Go" is phenomenal. Each song is carefully crafted, giving music lovers a taste of what's forthcoming from this band. Whether listeners prefer heavier rock 'n' roll or insightful ballads, this EP is sure to leave any listener wanting more.
